C. Baubet et al., Influence of tetragonal distortion on magnetic and magneto-optical properties of copper ferrite films, J PHYS CH S, 61(6), 2000, pp. 863-867
A series of copper ferrite films was prepared using RF magnetron sputtering
techniques. Annealing of the films at 450 and 650 degrees C in air brought
about changes of the tetragonal distortion of the spinel lattice enabling
to investigate the influence of the tetragonal distortion on magnetic and m
agneto-optical properties. Faraday rotations up to 2 degrees/mu m at 442 nm
, coercive fields up to 1800 Oe and high squareness of the hysteresis loops
up to 0.9 could be attained by 2 h annealing at 650 degrees C followed by
slow cooling. (C) 2000 Elsevier Science Ltd. All rights reserved.
