Abstract

PURPOSE:To stabilize the operation of a microwave element Ferry magnetic garnet material in the using temperature range of the garnet by employing the magnetic material of the predetermined composition formula satisfying the predetermined conditions, thereby reducing the temperature coefficient of the magnetic garnet material used for VHF band or the like. CONSTITUTION:A material represented by the composition formula (GdyY3-2x-y Ca2x)(Fe2-yIny)(Fe3-xVx)O12 satisfying the relation represented by the formulae: 0<x<=0.6, 0.3<=y<=0.6, 0.6<=z<1.5 and 1<=8x-28y+8z<=4 is weighed and is mixed by a ball mill. After the mixture is temporarily baked for the predetermined period of time, it is again pulverized by the ball mill, is then compression molded, and is baked at the predetermined temperature for the predetermined period of time in an oxygen atmosphere. Then, the temperature coefficient of the magnetic garnet material for the microwave element, e.g., circulator, isolator, etc. used for VHF, UHF bands, etc., and the temperature change of the element within the using temperature range can be simply varied.
