Abstract
A process for producing Ni-Mn-Zn ferrite single crystal for high frequency wherein a sample comprising 10-30 molar percent of NiO, 1.8-12 molar percent of MnO, 15-35 molar percent of ZnO and 49-53 molar percent of Fe.sub.2 O.sub.3 is melted and subjected to growing into a crystal under an oxygen partial pressure of below about 100 Kg/cm.sup.2.
