    • Abstract

       

      epr measurements on kainite containing Mn2+ impurities are made at x-band microwave frequencies at room temperature. The fine structure transitions observed inac* plane have helped to extract the spin Hamiltonian parameters of Mn2+ ions in the crystalline environment. The results indicate strong orthorhombic crystalline field and the rhombic field parameter is larger than those observed in the other similar systems. The z-axis of the D-tensor is determined with respect toac* plane by theoretically fitting the experimental fine structure transitions.
