Abstract
A variant of the quantum transfer-matrix method is used to obtain numerically accurate results for the specific heat of an easy-plane spin chain with an in-plane field, corresponding to the ferromagnetic compound CHAB. They are contrasted with predictions of the classical sine-Gordon approximation for the chain and with experimental data.
