Ultra Low Noise TMR Sensor by Tohoku University

Case Studies

Tohoku University in Japan is a major researcher of Tunnel Magneto-resistive (TMR) sensors. Their research is to develop novel materials and devices utilizing quantum spintronics. They are developing brain magnetic field sensing elements, spintronics-type quantum computing, and ultra-compact MRI system. As TMR sensors become more sensitive, it will be possible to detect even weak bio magnetic fields. The ultra-low noise TMR sensors are not only for biological signal applications, but it will dramatically be expanding the range of applications. Keysight E4727B Advanced Low-Frequency Noise Analyzer is an important solution for them.
