Abstract
The Electron Paramagnetic Resonance spectra of Cu 2+ doped cadmium formate dihydrate single crystal and powder were investigated in the temperature range from 300 to 133 K. The observed values of the g and A hyperfine tensors were found to be temperature dependent and this dependence is discussed. The angular variation of the spectra indicated the substitution of the host Cd 2+ with Cu 2+. Two magnetically inequivalent sites for Cu 2+ have been observed and the ground state wave functions of each site in the unit cell have been constructed.
