Patent AT-E400536-T1: [Translated] MAGNETIC FERRITE MATERIAL
Description
The present invention provides a ferrite magnetic material capable of attaining such magnetic properties that Br + (1/3) HcJ is 6200 or more even by sintering at a temperature of 1150°C or lower. The ferrite magnetic material includes as a main phase thereof a ferrite phase having a hexagonal structure, the main phase being represented by the following composition formula (1) : La x Ca m ± 1-x-m (Fe 12-y CO y ) z with ±, representing one or two of Ba and Sr; wherein the constituent ratios of the metal elements constituting the main phase satisfy the following conditions: x and m are the values in a region bounded by the points, A:(0.53, 0.27), B: (0.64, 0.27), C:(0.64, 0.35), D:(0.53, 0.45), E:(0.47, 0.45) and F: (0.47, 0.32) in the (x, m) coordinates shown in FIG. 2; 1.3 x/yz 1.8; and 9.5 12z 11.0.
