Abstract
We report the synthesis and characterisation of the spinel oxide Fe 2Mo 1− x Ti x O 4 (x = 0 to 1). The substitution of Ti in Fe 2MoO 4 shows interesting features in the Field Cooled and Zero Field Cooled magnetisation data. We observed a strong negative remanence and spin compensation temperature below Curie temperature. The results suggest the role of Mo in the double exchange interaction with systematic variation of T C with increasing Ti concentration. Field Cooled and Zero Field Cooled data measured under same field shows different compensation temperatures where the magnetic moment is minimum. Also applying a negative field resulted in the negative image of the same magnetisation.
