The Return of the Spin Echo
If the spins of phosphorus atoms in silicon are cleverly excited with microwave pulses, a so-called spin echo signal can be detected after a certain time. Surprisingly, this spin echo does not occur only once, but a whole series of echoes can be detected.

Macroscopic quantum interference in an ultra-pure metal
That visible light holds the character of a wave can be demonstrated in simple optics experiments, or directly witnessed when rainbows appear in the sky. Although the subtle laws of quantum mechanics, that is, wave mechanics, ultimately govern all the processes of electron transportelectrons in solids, their wave-like nature of the electrons is not often apparent to the casual observer.

Bose-Einstein condensate: magnetic particles behave repulsively
Data transmission that works by means of magnetic waves instead of electric currents - for many scientists, this is the basis of future technologies that will make transmission faster and individual components smaller and more energy-efficient. Magnons, the particles of magnetism, serve as moving information carriers.

New method for using spin waves in magnetic materials
Smaller, faster, more energy-efficient - this is the goal that developers of electronic devices have been working towards for years. In order to be able to miniaturize individual components of mobile phones or computers for example, magnetic waves are currently regarded as promising alternatives to conventional data transmission functioning by means of electric currents.

No escape for mosquitoes
Venus flytraps are capable of detecting the movements of even the smallest insects. This mechanism protects the plant against starving from hyperactivity as a new study conducted by scientists from Würzburg and Cambridge reveals. Physically bound to a specific location, plants have to devise special ways to secure their supply of vital nutrients.

Magnetism discovered in the Earth’s mantle: New findings on the Earth’s magnetic field
New findings on the Earth's magnetic field: researchers show that the iron oxide hematite remains magnetic deep within the Earth's mantle / Study published in "Nature" journal The huge magnetic field which surrounds the Earth, protecting it from radiation and charged particles from space - and which many animals even use for orientation purposes - is changing constantly, which is why geoscientists keep it constantly under surveillance.

A new spin on nanophysics: Part 2 of the series "Under lock and key at Münster University"
Part 2 of the series "Under lock and key at Münster University": the vacuum machine at the Institute of Physics is used to investigate spin phenomena The yellow stickers can already be seen from a distance: "Laser beam", "High voltage - danger to life", "No unauthorized access". The locked door with the warning notices is located at the end of a long, dark corridor on the fourth floor of the Institute of Physics at the University of Münster.

Closing the gap: On the road to terahertz electronics
Research news A team headed by the TUM physicists Alexander Holleitner and Reinhard Kienberger has succeeded for the first time in generating ultrashort electric pulses on a chip using metal antennas only a few nanometers in size, then running the signals a few millimeters above the surface and reading them in again a controlled manner.

Pacemakers on a roller test bench - TUM
Research news Pacemakers and defibrillators are often implanted in patients with heart failure or cardiac arrhythmias to regulate heart function. These devices are susceptible to electromagnetic interference, which can potentially occur in electric cars. In a recent study, however, a team led by Dr. Carsten Lennerz, a cardiologist at the German Heart Centre Munich and scientist at the German Centre for Cardiovascular Research (DZHK), concludes that current electric cars pose no threat to patients.

Virtual contact lenses for radar satellites
Research news Radar satellites supply the data used to map sea level and ocean currents. However, up until now the radar's "eyes" have been blind where the oceans are covered by ice. Researchers at the Technical University of Munich (TUM) have now developed a new analysis method to solve this problem.

Electrical steel: Strong magnetic fields due to sharp tools
Research news In an electric drive, magnetic fields have to be created in order to transform electric energy into kinetic energy. The magnetic properties of the motor's main components, referred to as electrical steel sheets, are the decisive factor in the efficiency of the electric motor. Scientists at the Technical University of Munich (TUM) have investigated the way these steel sheets are processed and have concluded that using blunt cutting tools deteriorates the magnetic properties of the steel sheets significantly.

Holography with the Wi-Fi-router
Research news Scientists at the Technical University of Munich (TUM) have developed a holographic imaging process that depicts the radiation of a Wi-Fi transmitter to generate three-dimensional images of the surrounding environment. Industrial facility operators could use this to track objects as they move through the production hall.

A new spin on electronics
Research news Modern computer technology is based on the transport of electric charge in semiconductors. But this technology's potential will be reaching its limits in the near future, since the components deployed cannot be miniaturized further. But, there is another option: using an electron's spin, instead of its charge, to transmit information.

Quasiparticles in time-lapse
Research news When an electron moves in solid matter, it polarizes its environment. Detailed insight into the interactions between electrons and their environment is the key to better performing future electronics components. However, since these processes transpire within only a few attoseconds, in the past they were practically impossible to investigate.

Mapping electromagnetic waveforms
Munich physicists have developed a novel electron microscope that can visualize electromagnetic fields oscillating at frequencies of billions of cycles per second. Temporally varying electromagnetic fields are the driving force behind the whole of electronics. Their polarities can change at mind-bogglingly fast rates, and it is difficult to capture them in action.

A switch for light wave electronics
Research news Light waves might be able to drive future transistors. The electromagnetic waves of light oscillate approximately one million times in a billionth of a second, hence at petahertz frequencies. In principle future electronics could reach this speed and become 100.000 times faster than current digital electronics.
