ABSTRACT:
A method of producing ferrite single crystals which comprises steps of melting a ferrite starting material in oxygen atmosphere containing nitrogen, argon or the like of a partial pressure of at least 0.1 atm. and solidifying the melt. According to this method, the popping out of the gas contained in the melt is prevented and the ferrite single crystals of high qualities can be produced easily.
