Abstract :
It is confirmed that collapse-field temperature coefficients 
of conventional YSmLuCaGeIG (SL) films varied in the range of -0.1 ∼ -0.3 %/°C in proportion to the molar ratio of Lu2 O3 /Sm2 O3 in the melt composition. of the SL system was found to be limited in the range of -0.21 ∼ -0.3 %/°C when considering the lattice parameter matching between GGG substrates and films. To obtain garnet films with of less than -0.2 %/°C, Er and Gd substituted garnet films were studied. YSmErGdLuCaGeIG films with of -0.10 %/°C and an YSmErCaGeIG films of -0.06 %/°C were obtained. From the resulting of and saturation magnetization temperature coefficient 
, it was derived that accounts for most of the .
