PROBLEM TO BE SOLVED : To provide a ferrite magnet exhibiting excellent characteristics and having an inexpensive magnetoplumbite crystal structure, and to provide its producing process.
SOLUTION : The ferrite magnet is composed of a single phase of magnetoplumbite crystal structure represented by a formula (Sr1-xAx)O-n[(Fe3+1-yMg2+y)2O3], where A is at least one kind being selected from rare earth elements, x, y and n represent mol ratios in the ranges of 0
