Laser MBE-grown yttrium iron garnet films on GaN: characterization of the crystal structure and magnetic properties

Yttrium iron garnet (YIG) films were grown on GaN substrates using the laser molecular beam epitaxy method. X-ray diffraction data showed polycrystalline YIG layers without additional structural modifications. The magnetic properties of the YIG films were studied at room temperature with the aid of...

Description
Summary:Yttrium iron garnet (YIG) films were grown on GaN substrates using the laser molecular beam epitaxy method. X-ray diffraction data showed polycrystalline YIG layers without additional structural modifications. The magnetic properties of the YIG films were studied at room temperature with the aid of a vibration sample magnetometer, the magneto-optical Kerr effect and ferromagnetic resonance methods. 'Easy-plane'-type magnetic anisotropy was found in the films. The gyromagnetic ratio and 4 πMS value were calculated.
