Specific features of electron spin resonance in quasi-1D magnet β-TeVO4
Abstract
The angular and temperature dependences of single crystal ESR spectra at X-band frequency of quasi-1D spin 1/2 antiferromagnetic zigzag chain system β-TeVO4 are reported. Two resonance components in the ESR spectrum have been detected: a weak narrow resonance on the top of the extremely broad signal. The narrow line might be due to an impurity, the characteristics of the broad absorption do not correlate with a picture of the typical behavior for the V4+ ions (S = 1/2) with a square pyramidal environment. It was found that at low temperatures the divergence of the spin susceptibility and linewidth of the observed excitations can be due to a realization of three dimensional magnetic ordering.
