In this article the authors present a  new method for torque magnetometry by using a commercially available membrane-type surface stress sensor (MSS) – the NANOSENSORS MSS. This sensor has a silicon membrane supported by four beams in which piezoresistive paths are integrated. Although originally developed as a gas sensor, it can be used for torque measurement by modifying its on-chip aluminum interconnections. The authors demonstrate the magnetic-torque measurement of submillimeter-sized crystals at low temperature and in strong magnetic fields. This MSS can observe de-Haas–van-Alphen oscillation, which confirms that it can be an alternative tool for self-sensitive microcantilevers.

NANOSENSORS is proudly sponsoring the Fourteenth International Workshop on Nanomechanical Sensors held at Kailua-Kona on the big island of Hawaii from 4-7 April 2017.

You will find more information on NANOSENSORS Membrane-type Surface Stress Sensors ( MSS) that can be used for nanomechanical sensing, electric nose, odor/flavor sensing, air quality monitoring, human breath analysis e.g.,for cancer research etc. in your conference bag or on the latest flyer on our website.

Prof. Ohmichi from Kobe University presented his first results on magnetometry using the NANOSENSORS Membrane-type Surface-stress Sensor (MSS) (NANOSENSORS special development code: SD-MSS-1K) at  the 72^nd Annual Meeting, the Physical Society of Japan (JPS) (Osaka University, Toyonaka Campus, March 17 – 20, 2017).
Congratulations to Professor Ohmichi for the excellent results!
