We report an EPR study of the quasi-two dimensional oxide Fe3O2BO3 which shows a structural transition at 283 K, an antiferromagnetic transition at 112K and weak ferromagnetism below 73 K. The single crystals show three strongly anisotropic lines with different temperature dependences of their widths and resonance fields. The results are discussed in relation with the different phase transitions and with the Wigner glass phase which appears between ~112 K and ~200 K.

AbstractGrowth conditions and electron paramagnetic resonance investigations of two well oriented KSm(WO4)2 and KEr(WO4)2 single crystals have been presented and discussed. Hyperfine structure of Sm3+ ion was detected and analyzed for angular and temperature dependences. EPR spectra of KEr(WO4)2 and its angular dependence showed the presence of 5 magnetically nonequivalent Er centers in the crystal. A change in the type of magnetic interactions was analyzed using mixed (Gaussian and Lorentzian) fits of the EPR spectra.
