Abstract
Two, NiFe/Co based spin valve structures, prepared by magnetron sputtering were studied by means of high-resolution Anger depth profiling. Strong inte rfacial mixing was found in the case of 'as deposited' specimens. A 2 h hea t treatment at 260 degrees C resulted in demixing, that is the width of int erfacial mixed zone became less than that in the 'as deposited' condition. (C) 2000 Elsevier Science S.A.
