PARAMAGNETIC IMPURITIES IN IONIC CRYSTALS.
Abstract
The report deals primarily with the results obtained on the systems LiF:Mn(2+) and Y2O3. The theoretical aspects of S-state transition metal ions in host-crystals is dealt with and applied to Mn(2+) in lithium fluoride. It is found that the method of molecular orbitals used to consider problems of limited covalency is not valid throughout the whole range of Mn(2+) F(-) bond distances. The possible role of ferromagnetic impurities in yttria and their relation to thermoluminescence in that materials is discussed. A point charge calculation of the crystalline electric field acting on Fe(3+) situated on the 8b site in vttria is detailed. The systems alpha-Al2O3, NaCl:Cu(2+) and NH4Cl:Mn(2+) are discussed briefly. (Author)
