Inhomogeneous Magnetic Field Influence on Magnetic Properties of NiFe/IrMn Thin Film Structures
arXiv:1811.02941 · doi:10.1016/j.jmmm.2018.10.013
Abstract
We demonstrate how the configuration and magnitude of a magnetic field, applied during magnetron sputtering of a NiFe/IrMn bilayer, influence the magnetic properties of the structure, such as hysteresis loop shape, coercivity, and exchange bias. Furthermore, we illustrate that it is possible to create a stepwise hysteresis loop in the sample's region with the highest field gradient. The found features can be used for future sensor applications.
