Effect of microstructural features and defects introduced by mechanical milling and thermal treatments on the magnetic order of spinel zinc
A wide range of different microstructures has been developed in ZnFe2O4 by combining a non-equilibrium processing route that introduces a significant amount of structural and microstructural defects, and thermal treatments. Previous results using XRD and SQUID magnetometry showed that the overall increase in magnetization with milling time is related with distribution of Zn+2 and Fe+3 cations and microstructural parameters like crystallite size and microstrain. However, the influence of other relevant structural parameter, like occupancy factor and special distribution of oxygen and the symmetry of the magnetic moments were not taken in account. We want to investigated the correct distributions of anions and cations and the magnetic and nuclear behaviour of 3 samples (as milled for 50h, and after annealing at 400 and 600ºC) at RT, 200,150, 100, 75, 50, 25 and 5K with the D2B high resolution diffractometer, and combining this study with the complete thermal variation of the diffraction patterns (1.5 - 300 K) obtained in the high intensity D1B diffractometer with 4 samples at a different level of structural disorder, i.e., after different milling times.
