Abstract

Abstract It was found experimentally that the critical curves of thin films with ferro-antiferromagnetic exchange coupling split into two branches when the hard axis field changes from positive to negative values or vice versa respectively, thus providing a very sensitive and easily detectable criterion for this coupling mechanism. The effect is interpreted according to a theory of Néel.
