Growth of Y3Fe5O12/GaN layers by laser molecular-beam epitaxy and characterization of their structural and magnetic properties

Laser molecular-beam epitaxy has been employed to obtain layers of yttrium-iron garnet (YIG) Y 3 Fe 5 O 12 on gallium nitride substrates. It was found that there exists a polycrystalline YIG phase without admixtures of other structural phases. A magnetic anisotropy of films of the “easy-magnetic pla...

Description
Summary:Laser molecular-beam epitaxy has been employed to obtain layers of yttrium-iron garnet (YIG) Y 3 Fe 5 O 12 on gallium nitride substrates. It was found that there exists a polycrystalline YIG phase without admixtures of other structural phases. A magnetic anisotropy of films of the “easy-magnetic plane” type was found. The gyromagnetic ratio and the demagnetizing field 4π M S were calculated.
