By diagonalizing the 120×120 complete energy matrices for d<Superscript>3</Superscript> ion in trigonal crystal field, which contains the electrostatic interaction, the trigonal field as well as the spin-orbit interaction, the unified calculation of the whole optical and EPR spectra for ruby are made. And matrix elements...</superscript>

The anisotropy spin-orbit coupling matrices for a d<Superscript>5</Superscript> configuration ion in a trigonal ligand-field have been established. On basis of the anisotropy spin-orbit coupling matrices, the ground state zero-field splitting of the Fe<Superscript>3+</Superscript> ions in ilmenite-structure MgTiO<Subscript>3</Subscript>:Fe<Superscript>3+</Superscript> system has been studied.

We use scanning tunneling microscopy to measure magnetic field induced strains in highly oriented pyrolytic graphite. This is done by using a scanning tunneling microscope with some magnetic components, which however do not produce an observable response within our resolution in the case of pure...
