Properties of Ce-substituted yttrium iron garnet film containing indium prepared by RF-sputtering

We studied the magneto-optical and magnetic properties of Ce-substituted yttrium iron garnet film containing indium. The magnetic anisotropy energy K u was estimated at -1.58×10 4 erg/cm 3 in the in-plane direction using ferromagnetic resonance. The λ 110 value is measured to be 1.56×10 -6 which is...

Description
Summary:We studied the magneto-optical and magnetic properties of Ce-substituted yttrium iron garnet film containing indium. The magnetic anisotropy energy K u was estimated at -1.58×10 4 erg/cm 3 in the in-plane direction using ferromagnetic resonance. The λ 110 value is measured to be 1.56×10 -6 which is much smaller than that estimated from other reported values. It appears that the measured K u can not be explained only in terms of the stress-induced magnetic anisotropy.
