Abstract
Low temperature thermodynamic quantities of quantum spin chains are obtained by combining the high temperature expansion and an argument based on the spin wave theory. The method is tested in the XY chain and applied to the Heisenberg chain for which low temperature specific heat and antiferromagnetic susceptibility are calculated.
