Title: MAGNETORESISTIVE ELEMENT HAVING AN ADJUSTABLE MAGNETOSTRICTION AND MAGNETIC DEVICE COMPRISING THE MAGNETORESISTIVE ELEMENT
Abstract:
The present disclosure concerns a magnetoresistive element (1) comprising: a storage layer (21) having a first storage magnetostriction; a sense layer (23) having a first sense magnetostriction; a barrier layer (22) between and in contact with the storage and sense layer (21, 23); wherein the magnetoresistive element (1) further comprises a compensating ferromagnetic layer (25) having a second magnetostriction different from the first storage magnetostriction and/or sense magnetostriction, and adapted to compensate the first storage magnetostriction and/or the first sense magnetostriction so that a net magnetostriction of the storage layer (21) and/or sense layer (23) is adjustable between -10 ppm et +10 ppm or more negative than -10 ppm by adjusting a thickness of the compensating ferromagnetic layer (25). The present disclosure concerns also concerns a magnetic device comprising the magnetoresistive element.
