Abstract

The field dependence of the magnetic heat capacity of (C6H11NH3)CuBr3 (CHAB), which is an ideal ferromagnetic S=(1/2) chain system with XY anisotropy, is compared with predictions based on the sine-Gordon (sG) model and with transfer-matrix calculations on a chain of classical spins. A detailed analysis of the excess heat capacity in the region 1.5
