Abstract

PURPOSE: To enable to agree the temperature coefficient of the magnetic bubble device with that of the permanent magnet, by taking the composite magnetic film forming the magnetic thin film having the in-surface magnetizing axis on one side as the chip of magnetic bubble.
CONSTITUTION: When (Y, Sm, Lu, Ca)2(Fe, Ge)5O12 garnette film having one axis magnetic anisotropy enabling to support the bubble axis is taken as the bubble magnetic domain material, the composite magnetic film Gd13Co82+(Y, Sm LU, Ca)3 (Fe, Ge)5O12 forming the magnetic thin film having the in-surface magnetizing axis on one side is taken as the chip of the magnetic bubble. The temperature change of the bubble relinquish magnetic field for the composite magnetic film is as shown in the curve 46, and the temperature coefficient of the magnetic bubble device is made agreed to that of the permanent magnet by making gentle only the bubble magnetic domain support layer in comparison with the temperature change curve 32 of the bubble relinquish magnetic field.
