Paper Abstract

Thermal stability of amorphous DyFeCo films covered with non-stoichiometric AlN layer has been investigated. When RE- dominated films were annealed in air for 10 hours at 200 degree(s)C, the Kerr loops showed the characteristic of magnetic double-layered films. This behavior can be interpreted as follows: the reaction of diffusing N with Dy leads to a reduction of the magnetic active Dy content at the interface and created a very thin TM dominated DyFeCo layer between AlN and DyFeCo layer. This interpretation was demonstrated by XPS measurements.
