Time-of-flight inelastic scattering from polycrystalline samples of AgVP2S6 and AgCrPzS6 has revealed characteristic features of integer and half-integer spin antiferromagnetic chains. In the S = 1 system we have followed the temperature dependence of the Haldane-gap mode in a wide temperature range
Magnetic properties of quasi-one-dimensional S ¼ 1=2 Heisenberg antiferromagnet Sr 2 Cu(PO 4 ) 2 were investigated by temperature and field dependence of AC susceptibility down to 0.03 K. A sharp peak was observed at T N ¼ 0:085 K on the temperature dependence of AC susceptibility indicating long-ra
