(Received November 25, 2002; accepted for publication January 15, 2003)

Ni_0.3Mn_xZn_0.7-xFe₂O₄ samples, with x=0.1, 0.2, 0.3, 0.4, 0.5, have been prepared by the citrate precursor method and their dc resistivity, complex initial permeability, permittivity and saturation magnetization are studied. Initial increase followed by a decrease is observed in dc resistivity and saturation magnetization (maximum 57 emu/gm) with increase in x. Initial relative permeability is observed to decrease from 550 to 100 with increase in manganese content. A shift in dielectric relaxation peak towards higher frequencies is observed with increase in x. A slight variation of resistivity is observed with increasing applied field.
