We have investigated the chromium-iron alloy and compared it to the oxides α-Fe2O3 (Eg = 4.8eV) and α-Cr2O3 (Eg = 2.1eV). It is known that α-Cr2O3 and α-Fe2O3 both adopt a corundum-type structure, but display differences in the lattice constants, direct band gap, and magnetic ordering of the cations. The chromium-iron alloy was synthesized by thermal diffusion processes of both chromium and iron thin-films in air atmosphere conditions. We have studied the elastic distortions related to nature of the relative strains as well as magnetic coupling between Fe and Cr from the X-ray diffraction studies.

Basaltic Magmas

The width (W) of plagioclase crystallizing from magmas is given by the equation log [Formula: see text] where t is the crystallization time calculated from Jaeger's model and η is the viscosity of a magma. The values log 2η−1/3 for basaltic and granitic magmas under hydrous and anhydrous conditions are −0.1 and −1.0 for basaltic magmas, and −1.5 and −3.5 for granitic magmas, respectively. The equation can be explained by coarsening, thermal diffusion, and (or) material diffusion processes.
