ABSTRACT:
A non-magnetic single crystal of Mn--Zn ferrite obtained by a solid phase reaction process including the steps of contacting a seed single crystal ferrite with a polycrystal crystal ferrite and producing the single crystal by growing the single crystal in a direction from the seed single crystal toward the polycrystal under heating. The single crystal of Mn--Zn ferrite has a composition defined by points A, B, C, D and E in a three-phase diagram of Fe.sub.2 O.sub.3 --MnO--ZnO, in which:
