The EPR Study of Mn2+ Ion Doped DADT Single Crystal Produced under High Pressure and Temperature

Abstract

An EPR study on Cu2+ and VO2+ doped di ammonium D-tartrate single crystals has been reported in previous papers, but the same host did not accept Mn2+ ion at the same reaction conditions in previous trials. In this study EPR study of Mn2+ ion doped di ammonium D tartrate single crystal, (DADT) [(NH4)(2)C4H4O6], produced in a reactor under high pressure and high temperature. The electronic transitions were determined by the optical absorption spectrum. Hyperfine splitting and g values of the Mn2+ ion forming a complex in the lattice were measured from experimental spectra and spin spin dipolar splitting parameters D and E were found by the spectrum simulation techniques.
