MAGNETIC-PROPERTIES OF FE2MO1-XTIXO4

We report the synthesis and characterisation of the spinel oxide Fe2Mo 1-xTixO4 (x = 0 to 1). The substitution of Ti in Fe2MoO4 shows interes ting features in the Field Cooled and Zero Field Cooled magnetisation data. We observed a strong negative remanence and spin compensation te mperature below Curie temperature. The results suggest the role of Mo in the double exchange interaction with systematic variation of T-C wi th increasing Ti concentration. Field Cooled and Zero Field Cooled dat a measured under same field shows different compensation temperatures where the magnetic moment is minimum. Also applying a negative field r esulted in the negative image of the same magnetisation. (C) 1997 Publ ished by Elsevier Science Ltd.
