AbstractA spin-glass state up to 210 K has been found in (Mg,Fe){Mg,Fe,Ti)2O4 spinel ferrite thin films formed on α-Al2O3(0001) substrates. The long-time relaxation of the magnetization in zero-field-cooled operation, which is characteristic feature of the spin-glass state, has been observed below 210 K. We have also achieved the change of magnetic state in the film from spin-glass to ferrimagnet over a wide temperature range below 160 K by means of light-irradiation. The amount of spin-melt on light-irradiation is calculated to be 41 % at 10 K and 26 % at 100 K.
