An Mn-Zn-based single crystal ferrite composition containing an additive material essentially consisting of 0.2 to 2 mole % SnO.sub.2, 0.1 to 1 mole % CoO, 0.2 to 1 mole % CaCO.sub.3 and 0.02 to 1 weight % V.sub.2 O.sub.5 added to a host material essentially consisting of 51 to 54 mole % Fe.sub.2 O.sub.3, 27 to 33 mole % MnO and 16 to 20 mole % ZnO. A magnetic head manufactured from the single crystal ferrite generates an enhanced reproduction output and a reduced rubbing noise, thereby achieving a high picture quality and a high resolution of images.
