Magnetotaxial Perpendicular Magnetic Anisotropy and Enhanced Faraday Rotation in Ion Beam Sputtered Cerium-Substituted Yttrium Iron Garnet.

ABSTRACT: Ferrimagnetic iron garnets are valuable for photonic and spintronic devices because of their large magnetooptical (MO) effects and tunable magnetic anisotropy and domain structures. In particular, cerium-substituted yttrium iron garnet (Ce:YIG) has an excellent MO figure of merit in the near-infrared region. However, achieving perpendicular magnetic anisotropy (PMA) in Ce:YIG films has conventionally relied on strain engineering, constraining the relationship between substrate lattice parameters and magnetic properties. We demonstrate strain-independent PMA in epitaxially grown Ce:YIG (Ce_0.9Y_2.1Fe₅O₁₂) films on two different (111)-oriented garnet substrates using ion beam sputtering. Despite opposite strain states (tensile and compressive), both
