NiFe2-xDyxO4 (x = 0, 0.1) compounds were prepared by solid state reaction. Room temperature X-ray diffraction confirmed the formation of the compounds in cubic inverse spinet phase with the space group Fd (3) over barm. Increments in the lattice constant were observed upon partial substitution of Fe3+ by Dy3+. While both magnetization and cubic magnetocrystalline anisotropy (K-1) decreased with increasing temperature, with Dy3+ substitution, at any given temperature the magnetization decreased and K-1 increased. A quantitative observation of direct magnetoelectric (DME) effect and qualitative observation of converse magnetoelectric (CME) effect in NiFe19Dy0.1O4 compound, describe its multiferroic nature.
