MnZn ferrites have been produced via the high-energy ball milling of binary oxide precursors. The milled ferrites have a nonequilibrium cation site distribution with an unusually high population of Zn cations on the octahedral sites. The particle sie distribution drops precipitously with milling time from 601 to 141 nm at 10 h but increases to 18.51 nm after long durations 20-40 h
