New Method for Torque Magnetometry Using a Commercially Available Membrane-Type Surface Stress Sensor

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.

探針がカンチレバー先端より突出し、直上から探針先端を観察可能。NANOSENSORS アドバンスドテック AdvancedTEC™ (ATEC) プローブ

アドバンスドテックシリーズはシャープな三角錐の探針がカンチレバー先端より更に前方へと突き出ているのが特長。

探針を確実に測定領域にポジショニングしたい場合や、探針先端を直接見ながら作業するナノマニピュレーションなどのアプリケーションに最適です。

Happy Swiss National Holiday with Smallest Swiss Cross

Basel University : Smallest Swiss Cross – Made of 20 Single Atoms ( a NANOSENSORS PPP-NCL was used for this image)

20 bromine atoms positioned on a sodium chloride surface using the tip of an atomic force microscope at room temperature, creating a Swiss cross with the size of 5.6nm. The structure is stable at room temperature and was achieved by exchanging chlorine with bromine atoms. (Fig: University of Basel, Department of Physics), image made with NANOSENSORS PPP-NCL AFM tip
