Abstract

We investigated the magnetic properties in Ru (Eu1.5 Ce0.5) Sr2 Cu2 O10-δ (Ru-1222) epitaxial films. Large magnetic anisotropy was observed, showing that the c axis is the hard axis of magnetization, while all the directions in the ab plane are isotropic easy axes for magnetization. A possible arrangement of the Ru moments is suggested to interpret the magnetic anisotropy as well as the complex magnetic properties of Ru-1222 including the ferromagnetic, the antiferromagnetic, and the spin-glass behaviors.
