Flexible giant magnetoresistance sensors

Exchange-biased magnetic sandwiches are shown to exhibit "giant" magnetoresistive properties when deposited on free-standing organic films. This allows for the possibility of preparing flexible magnetoresistance heads or head arrays for tape or floppy-disk drive and hard-disk drive applications. Similar structures deposited on thin organic layers spin coated onto silicon substrates also exhibit giant magnetoresistive behavior.© 1996 American Institute of Physics. [S0003-6951(96)04846-2].
