EPR study of the ground state of Mn2+ impurity ions in alumoborates MAl3(BO3)4 (M=Y, Eu, Tm)

Original language description

New data about the ground state of the Mn2+ impurity ions in a series of single crystals of alumbrados MAl3 B03)4, where M= Y,Eu,Tm were obtained. The electron paramagnetic resonance (EPR) spectra of the Mn2+ spectra were studied, the parameters of the spin Hamiltonian describing the angular dependence of the spectrum were defined. It was shown that Mn2+ ions substitute trivalent ions of rare earth metals without changing the symmetry of the substitution site. The charge compensation process was found to be a nonlocal one. The cooling of the crystals leads to the increase of the splitting of the ground state, which is associated with the anisotropy of the thermal expansion coefficient. It was shown that an application of the superposition model to explain the distortions induced by an impurity Mn2+ ion has some limitations.
