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 Fe2O3-MnO-ZnO, in which: A: Fe2O3 40 mol %, MnO 10 mol %, ZnO 50 mol %; B: Fe2O3 40 mol %, MnO 35 mol %, ZnO 25 mol %; C: Fe2O3 70 mol %, MnO 5 mol %, ZnO 25 mol %; D: Fe2O3 70 mol %, MnO 2 mol %, ZnO 28 mol %; and E: Fe2O3 48 mol %, MnO 2 mol %, ZnO 50 mol %.
