Abstract

1281498 Ferrimagnetic garnets NIPPON ELECTRIC CO Ltd 19 April 1971 [3 April 1970 1 July 1970] 26227/71 Heading H1H Ferrimagnetic modified calcium-vanadium garnets have the formula where and values of x and y such that 0À8#3x+y#1À2 are excluded. In one embodiment, the garnets have the formula where and values of x, y and z such that are excluded. The garnets show a small temperature variation of saturation magnetization value (4#Ms) and low ferromagnetic resonance linewidth (#H 125 or less) coupled with a high Curie temperature. In one example, a value of #H = 2À5 is obtained by polishing the garnet into spheres.
