Three-axis torque investigation of interfacial exchange coupling in a NiFe/CoO bilayer micromagnetic disk

M. G. Dunsmore, J. A. Thibault, K. R. Fast +5

Micrometer diameter bilayers of NiFe (permalloy, Py) and cobalt oxide (CoO) deposited on nanomechanical resonators were used to investigate exchange bias effects. The mechanical co…
