ABSTRACT:
Provided is a magnetoresistance device. The device includes a substrate, a lower layer formed on the substrate, and a magnetoresistance structure formed on the lower layer, and the lower layer is formed of amorphous ZrxAl1-x(0<x<1) or ZrxAl1-xOy(0<x<1, 0<y<1). In a tunneling magnetoresistance (TMR) device, a tunneling barrier layer is formed of at least one selected from the group consisting of ZrxAl1-xOy(0<x<1, 0<y<1), TixAl1-xOy(0<x<1, 0<y<1), and NbxAl1-xOy(0<x<1, 0<y<1).
