Determination of the Saturation Magnetization from Perpendicular Magnetic Anisotropy Measurements of Ion Irradiated Multilayers
Markó, D.; Strache, T.; Lenz, K.; Fassbender, J.ORC; Kaltofen, R.
Thin films and superlattices of Py/Ta with an overall Py thickness of 20 nm and different number of Py/Ta stacks were irradiated with Ne ions in order to study the influence of interfacial mixing on their magnetic properties. With both, increasing ion fluence and increasing number of Py/Ta interfaces, a decrease of saturation magnetization and an increase of damping can be observed. However, the small uniaxial anisotropy of the samples remains unaffected. The critical ion fluence at which ferromagnetism, depending on the number of interfaces, vanishes has been determined.
