The Scanning TMR Microscope for Biosensor Applications

The Scanning TMR Microscope for Biosensor Applications

We present a novel tunnel magnetoresistance (TMR) scanning microscopeset-up capable of quantitatively imaging the magnetic stray field patterns of micron-sizedelements in 3D. By incorporating an Anderson loop measurement circuit for impedancematching, we are able to detect magnetoresistance changes...
