Studies on the magnetic properties of nanocrystalline ZnFe2O4 synthesized by an autocombustion method are reported. Superparamagnetic behavior is observed for the nanocrystalline materials with particle sizes of 8 nm and 17nm, with superparamagnetic blocking temperatures of 65 K and 75 K, respectively. Magnetic hysteresis with very large coercivities of 533 Oe and 325 Oe, respectively, are observed at 12 K. Studies on the temperature variation of the magnetization above room temperature indicate that the Curie temperature is as high as ∼800 K when compared to the paramagnetic nature of bulk zinc ferrite at room temperature.

The ε33T/ε0 and d33 values of ACP 0.66PIN–0.34PT crystals are shown to be 3070 and 1400 pC N−1, respectively, which are 14% and 18% larger than those of a DCP sample, owing to the enhancement of both intrinsic and extrinsic contributions.
