NASA's X-ray space telescope IXPE has made the first observation of polarized light emerging from an outbursting magnetar, neutron stars that possess the universe's strongest magnetic fields.

The job of a catalyst is to ultimately speed up reactions, which could reduce an hour-long process into several minutes. It has recently been shown that using external magnetic fields to modulate ...

New 2D quantum sensor breakthrough offers new opportunities for magnetic field detection Date: May 28, 2025 Source: University of Cambridge Summary: Physicists have unveiled a breakthrough in ...

In contrast, the hBN sensor development by the team in Cambridge does not share these limitations and instead presents a multi-axis sensor of magnetic field with large dynamic range.

The passive PT-symmetric model for SAW sensor. a The schematic diagram of the coupled resonators model and the real part of the eigenfrequency surfaces in the parameter space (ω1 = ω2 = ω0 = 0,γ0 = 0) ...

Surface acoustic wave (SAW) sensors with ferromagnetic materials are used to measure magnetic fields or electric currents. The magnetic field sensitivities of SAW magnetic field sensors are ...

Note that the frequency position of the best sensitivity of the magnetic field sensor is related to the mechanical mode of the resonator. It can be tuned by adjusting the frequency position of the ...

A technical paper titled “Impact of external magnetic fields on STT-MRAM” was recently published by researchers at Univ. Grenoble Alpes, Everspin, GlobalFoundries, imec, et al. Abstract “This ...

The maximum field tolerance of these MRAM devices is between a few tens of milliTesla, mT, to 100mT, depending upon the MRAM target application. 10mT in SI units is 100G in CGS units of magnetic ...

The most established piezoelectric material-based MEMS technology uses zinc oxide (ZnO) thin films, which are widely used in film-bulk acoustic-wave resonators, surface acoustic wave resonators, ...
