More Information
Summary:Disclosed is an oxide magnetic material which includes a ferrite having a hexagonal structure as a main phase. The metal elements contained in the oxide magnetic material are expressed as the following formula: Ca1-x-x'LaxSrx'Fe2n-yCoy, and x, x' and y representing atomic ratios and n representing a molar ratio satisfy the following relations: 0.4 = x = 0.6, 0.01 = x' = 0.3, 0.2 = y = 0.45, 5.2 = n = 5.8. La présente invention concerne un matériau magnétique de type oxyde comprenant une ferrite ayant une structure hexagonale en tant que phase principale. Les éléments métalliques contenus dans le matériau magnétique de type oxyde sont représentés par la formule suivante : Ca1-x-x'LaxSrx'Fe2n-yCoy, x, x' et y représentant des rapports atomiques et n représentant un rapport molaire satisfaisant les relations suivantes : 0,4 = x = 0,6, 0,01 = x' = 0,3, 0,2 = y = 0,45, 5,2 = n = 5,8.
