Abstract

We report on the growth and magnetic characterization of epitaxial garnet thin films and heterostructures by pulsed laser deposition. Thin films and heterostructures consisting of yttrium iron garnet (YIG) interleaved with rare earth substituted bismuth iron garnet (BIG) have been deposited on single-crystal GGG substrates. These heterostructures exhibit strong polar magneto-optic Kerr effects with rotation angles of better than 5×104 °/cm at 533 nm. Microwave measurements at 10 GHz suggest that the Eu-substituted BIG layer has a preferred out-of-plane magnetization while the YIG layer is still magnetized in-plane. The implications of the magneto-optic and microwave results will be discussed in light of the heterostructure periodicity and film microstructure.
