Electron paramagnetic resonance of Cu 2+ in Cd(NH 4) 2(SO 4) 2 · 6H 2O

Abstract

The electron paramagnetic resonance spectra of Cu 2+ in Cd(NH 4) 2(SO 4) 2 · 6H 2O powder and single crystals have been recorded at 300 K and 113 K. 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. The spectra were fitted with a rhombic spin Hamiltonian and the Hamiltonian parameters were determined. The g and A tensors were found to be coaxial within the limits of experimental errors and the ground state wavefunction of the complex has been constructed.
