| La-, Lu-, and Sc-substituted yttrium iron garnet films with thickness of 100 nm were grown by liquid phase epitaxy method using two types of fluxes - PbO-B2O3 and Li2MoO4-Y2(MoO4)3. The processes of in-plane reversal magnetization and ferromagnetic resonance were investigated. Obtained parameters are compared with parameters of micrometers thick films with the same compositions. The 100 nm thin films demonstrate small in-plane saturations field and low Gilbert damping constant (~10-4). The prospects of using lead-free flux are shown. |
