Electrical manipulation of ferromagnetic NiFe by antiferromagnetic IrMn
Electrical manipulation of ferromagnetic NiFe by antiferromagnetic IrMn
We demonstrate that an antiferromagnet can be employed for a highly efficient electrical manipulation of a ferromagnet. In our study we use an electrical detection technique of the ferromagnetic resonance driven by an in-plane ac-current in a NiFe/IrMn bilayer. At room temperature, we observe antidamping-like spin torque acting on the …
