Magnetooptical microwave spectroscopy of the coherent magnetic state in the mixed valence compound SmB6 in the frequency range 40-120 GHz
JETP Letters 64:10 (1996) 760-766
Abstract:
In undoped pure single crystals of the mixed valence compound SmB6 anomalous ESR absorption is observed in the frequency range v=40-120 GHz at temperatures of 1.8-4.2 K. The ESR for the case of the coherent ground state consists of two components corresponding to g-factors g1=1.907±0.003 and g2=1.890±0.003. The amplitude of both ESR lines strongly depends on temperature in the temperature range studied: the amplitude of the first line with g=gt increases and the amplitude of the second line decreases with temperature. A model based on consideration of intrinsic defects in the SmB6 crystalline lattice, with a density ∼1015-1016 cm-3, is suggested as an explanation for the anomalous ESR-behavior. In the frequency range v>70 GHz at T=4.2 K, in addition to the main ESR lines, a new magnetic resonance with a hysteretic field dependence is discovered. © 1996 American Institute of Physics.Magneto-optical studies of magnetic defects in CeNiSn

Abstract:
Millimetre wave magnetotransmission measurements are used to provide the first clear evidence for magnetic defects in CeNiSn. At least two defect configurations are observed, both probably involving Ce3+ ions.EPR of Photoexcited Triplet State Acceptor Porphyrins
