A magnetic compound is expressed by an equation (R_(1-x)Zr_x)_a(Fe_(1-y)Co_y)_bT_cM_dA_e (in the same equation, R is a rare earth element of one type or more, and T is an element of one type or more selected in a group comprising Ti, V, Mo and W, and M is an inevitable impurity element and is an element of one type or more selected in a group comprising Al, Cr, Cu, Ga, Ag and Au; and A is an element of one type or more selected in a group comprising N, C, H and P, and 0 <= x <= 0.5, 0 <= y <= 0.6, 4 <= a <= 20, b = 100-a-c-d, 0 < c < 7, 0 <= d <= 1, 1 <= e <= 18). A main phase of the magnetic compound has a ThMn_12 type crystalline structure, and a volume fraction of α-(Fe,Co) phase is 20% or less. |
