摘要:Spin-torque induced magnetization dynamics in a magnetoresistive nanopillar with a conically magnetized free layer and an in-plane magnetized reference layer is theoretically studied. Two modes are observed for zero-bias-field self-oscillation, the occurrence of which depends on ...

摘要:A magnetic tunnel junction (MTJ), which consists of a thin insulating layer (a tunnel barrier) sandwiched between two ferromagnetic electrode layers, exhibits tunneling magnetoresistance (TMR) due to spin-dependent electron tunneling. Since the discovery of room-temperature ...

摘要:The crystalline structure of FeRh0.38Pd0.62 alloy was examined by means of X-ray diffractometry. In this alloy, a new ferromagnetic phase was found below 265 K in the matrix body-centered tetragonal phase. The low-temperature phase has an orthorhombic struct...

摘要:Magnetic phase transitions in bcc FeRh0.95Ir0.05 alloy were investigated under high pressures up to 6.2 GPa by means of X-ray diffractometry using synchrotron radiation. The phase transition from antiferromagnetic to paramagnetic at high pressures with incre...
