Magnetic Interaction between Ferromagnetic Minerals Contained in Rocks (II)

Magnetic Impurity States and Ferromagnetic Interaction in Diluted Magnetic Semiconductors

The electronic structure of diluted magnetic semiconductors is studied, especially focusing on the hole character. The Haldane-Anderson model is extend to a magnetic impurity, and is analyzed in the Hartree-Fock approximation. Due to the strong hybridization of an impurity d-states with host p-states, it is shown that holes are created in the valence band, at the same time the localized magneti...

Elasticity of Selected Rocks and Minerals

been the subject of numerous investigations (Birch, 1960, 1961). In this study, measurement of bulk density and of compressional and rotational wave velocities of a variety of rocks and minerals affords the opportunity of calculating elastic constants and of studying anisotropy in elastic velocities. Although it was not possible to take into account the effect of confining pressure on velocitie...
