Beschreibungen/Notizen

• The electron paramagnetic resonance (EPR) of Sm3+ ion in KY(WO4)2 single crystal was investigated at T = 4.2 K using an X‐band spectrometer. The observed resonance absorption represents the complex superposition of three spectra corresponding to samarium isotopes with different nuclear moment. The EPR spectrum is characterised by a strong g ‐factor anisotropy. The temperature dependences of the g ‐factor were shown to be caused by strong spin–orbital and orbital–lattice coupling. The resonance lines become broader as temperature increases due to the short spin–lattice relaxation time. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
