| Abstract: | An EPR study of Mn2+ in (NH4)2Ni(SeO4)2·6H2O crystals has been reported for the first time at room temperature (≈300 K) and at the X-band. The observations regarding the anisotropic and field dependent linewidths of Mn2+ in nickel Tutton salts at room temperature are discussed in terms of the spin quenching ideas. Also, the gz-shift in Mn2+-doped Ni-Tutton salts is attributed to the internal magnetic field at the site of the Mn2+ ion, caused by the moments induced on Ni2+ ions. |
