PROBLEM TO BE SOLVED : To obtain a magnetic material which can be fired at a low temperature by a method wherein at least Y or one or more kinds of rare-earth metal elements, Fe and O are contained as main compositions, one or more kinds of V, Cu, Mo, W and Pb in specific amounts are contained as subcompositions and the main compositions comprise a garnet-type structure. SOLUTION : At least yttrium (Y) or one or more kinds of rareearth metal elements iron (Fe) and oxygen (O) are contained as main compositions. When the main compositions are used in 100 pts.wt., subcompositions comtain one or more kinds out of vanadium (V) in 0
