Effect of cation substitution on the magnetic and magnetotransport properties of epitaxial Fe3−xVxO4 films

Experimental Determination of the Standard Gibbs Energy of Formation of Fe3–xVxO4 at 1473 K

“…Wakihara et al [14] synthesized the spinel solid solution with stoichiometric composition at 1500 K under controlled CO 2 -H 2 atmospheres, measured the Curie temperature and the magnetization behaviors of a series of solidsolution compounds, and proposed a magnetic structure model. Jin et al [15] fabricated epitaxial Fe 3-x V x O 4 (0 ≤ x ≤ 0.6) films by using reactive co-sputtering from pure Fe and V in a gas mixture of Ar and O 2 , and the magnetic and magnetotransport properties of the film spinels were studied at room temperature. Pool et al [16] synthesized nanoparticles of Fe 3-x V x O 4 with up to 33% vanadium substitution (x = 0 to 1) by mixing appropriate ratios of solutions of 0.5 mmol V(acac) 3 and Fe(acac) 3 , 1,2-hexadecanediol with benzyl ether, oleic acid(1.5 mmol), and oleylamine (1.5 mmol) under evacuated conditions.…”
