Using magnetic tunnel junctions to probe quantum properties of materials

ORAL

Abstract

Magnetic tunnel junctions (MTJ) are ultra sensitive, low noise devices that can operate in extreme environmental conditions such as high electric and magnetic fields and low temperatures. MTJs can detect magnetic fields to picoTesla sensitivity, have spatial resolution on a relevant mesoscopic length scale and frequency sensitivity from DC to several GHz, and can operate in zero or finite applied electric or magnetic fields. In this talk, we will present modes in which MTJ based-sensors can be optimized to probe quantum properties of materials.
