Specific-heat of (c6h11nh3)cubr3 and (c6h11nh3)cucl3 within series analysis of finite-chain data

摘要

The in-plane specific heat of the title compounds has been estimated by analysis of the finite-chain data in the framework of new polynomial extrapolations, displaying better convergence properties for 1/N -> 0. Final results are consistent with those we found previously for the linear and parabolic extrapolations, as well as reveal an agreement with experiment and recent quantum transfer-matrix simulations.
