β¦ Synopsis
An alternating heat flow method is used to measure the heat capacity of metals at low temperatures under hydrostatic compression. The phase shift method is developed for taking account of the losses in the medium. The method was tested by measuring the heat capacity of Sn at pressures up to 10 k bar. The errors of measurement are ~3%.
