Structural and Magnetic Properties of Ni0.8Fe0.2/Ti Nanoscale Multilayers

The influence of the thickness of the Ni0.8Fe0.2 (Permalloy, Py) layers on the structural and magnetic properties of magnetron sputtered Py/Ti multilayers was studied. The thickness of the Py layers was varied in the interval of 8 to 30 angstrom. X-ray reflectivity scans evidence the existence of a...
