Electron paramagnetic resonance (EPR) studies of Mn2+ impurity in single crystals of diammonium hexaaqua magnesium(II) sulfate have been carried out at 9.3 GHz (X-band) at room temperature. The EPR spectra exhibit a group of five fine structure transitions. The spin-Hamiltonian parameters were determined. Mn2+ enters the lattice interstitially. The EPR spectrum of a powder sample supports the data obtained by single crystal studies. - PACS number: 76.30

The spin-Hamiltonian parameters describing the EPR spectrum of Mn2+ in CsCl crystals grown from solutilon have been determined. The line-width data are in agreement with the manganese ions being incorporated interstitially rather than substitutionally for Cs+ ions. From the work on Mn2+ in NH4Cl we infer that the fine structure parameter, D2, is negative.

An electron paramagnetic resonance study of Mn2+ in K2Ni(SeO4)2∙6H2O single crystals has been made at 294 K and 9.45 GHz. The Mn2+ substitutes at Ni2+ sites in the lattice. The spin-Hamiltonian parameters are evaluated. The observations regarding the anisotropic and field dependent line widths of Mn2+ in the lattice are discussed using the spin-quenching concept.

ABSTRACTThe technique of electron paramagnetic resonance has been applied to study the magnetic properties of nickel acetate and nickel potassium tutton salt single crystals, using Mn2+ ion as probe. From the values of spin Hamiltonian parameters and linewidths at room, liquid nitrogen and liquid helium temperatures it is concluded that these crystals do not become magnetically ordered as the temperature is lowered to 3.2K, and thus the transition temperature, below which the crystal would order either ferromagnetically, or antiferromagnetically, for these crystals, should be below 3.2K.

The results of an electron paramagnetic resonance (EPR) study of vanadyl ion VO2+ doped in single crystals of Ba(ClO4)2 - 3 H2O are reported. The spectra indicated the presence of two substitutional and interstitial sites depending on the orientation. The spin-Hamiltonian parameters were determined from single crystal and powder EPR data. These parameters were found to be axial symmetric for the powder sample, whereas they showed deviations from axial symmetry for the single crystal

An electron paramagnetic resonance (e.p.r.) study at 9.1 and 12.0 GHz on polycrystalline copper(II) benzoate has given the following Spin Hamiltonian parameters for the binuclear molecule: D = 0.3311 ± 0.0006 cm−1, E = 0.0147 ± 0.0003 cm−1, gx = 2.048 ± 0.004, gy = 2.074 ± 0.004, gz = 2.345 ± 0.004. Using the average g value of 2.160 ± 0.004 obtained from e.p.r. and previously published magnetic susceptibility studies, 2J is estimated to be 333 cm−1.
