Abstract

PURPOSE: To lessen the temperature coefficient of saturation magnetization, by making a temperature exhibiting the maximum saturation magnetization between the compensation point of magnetization and the Curie temperature of a microwave ferrimagnetic garnet shown by a specific composition formula be in a specific range.
CONSTITUTION: A microwave garnet has a composition shown by the formula, and x, y, and z in the formula have the following relation-ship, 0<x≤0.7, 0.05≤y< 0.2, 0.6≤z≤1.85. A temperature exhibiting the maximum saturation magnetization between the compensation point of nagnetization and the Curie temperature is in a range -20W30°C. The reason why Y, the amount Sn, is limited to 0.05≤Y≤ 0.2 is that in case that y is ≤0.05, the half value width of ferromagnetic resonance absorption is increased abruptly and in case that y is ≥0.2, the temperature coefficient of the saturation magnetization is enlarged abruptly.
