STATIC MAGNETIC CHARACTERISTICS NONUNIFORM OVER THE THICKNESS OF CONIFILMS

A method based on the meridional magnetooptical intensity effect is us ed to study the hysteresis loops on opposite sides of thin cobalt-nick el films deposited at a varying angle on a polyethyleneterephthalate s ubstrate. A comparison of the magnetic propertes of the films on the d ifferent sides and in the bulk show that these properties change conti nuously over the thickness. The coercivity is always greater on the si de of the film where the angle of deposition is higher. The difference in the magnetic characteristics on the opposite sides of the film is greater in thicker films, (C) 1997 American Institute of Physics.
