Beta-TeVO4 behaves as a 1D S=1/2 Heisenberg antiferromagnet
Abstract
The magnetic susceptibility and magnetization of high quality single crystal beta-TeVO4 are reported. We show that this compound, made of weakly coupled infinite chains of VO5 pyramids sharing corners, behaves as a S = 1/2 one-dimensional Heisenberg antiferromagnet. From magnetic experiments we deduce the intrachain antiferromagnetic coupling constant J/kB = 21.4 0.2 K. Below 5 K a series of three phase transitions at 2.26, 3.28 and 4.65 K is observed.
