Abstract
The disclosure relates to spin orbit torque (SOT) magnetic random access (MRAM) devices. A magnetic structure for a SOT-MRAM device and a method for fabricating the magnetic structure are presented. The magnetic structure comprises a SOT layer and a magnetic tunnel junction (MTJ) structure arranged on the SOT layer. The SOT layer comprises a material combination of a bismuth-based material and a metal having a melting point of at least 1000° C. As a result, the SOT is thermally stable and also shows a large spin Hall angle (SHA).
