采用脉冲激光沉积法在（100）取向的钆镓石榴石（GGG，Gd3Ga5O12）衬底上外延生长了钇铁石榴石（YIG，Y3Fe5O12）薄膜。薄膜为单相，与GGG衬底外延，均方根表面粗糙度在0.14 nm和0.2 nm之间变化。厚度在17至200 nm范围内的膜表现出低的介电常数（
Yttrium iron garnet (YIG, Y3Fe5O12) films have been epitaxially grown on Gadolinium Gallium Garnet (GGG, Gd3Ga5O12) substrates with (100) orientation using pulsed laser deposition. The films were single-phase, epitaxial with the GGG substrate, and the root-mean-square surface roughness varied between 0.14 nm and 0.2 nm. Films with thicknesses ranging from 17 to 200 nm exhibited low coercivity (
