摘要: A technique is described which permits the accurate measurement of heat capacities to very low temperatures without use a switch. As test this specific Cu, with and hydrogen impurities, has been measured in temperature range 0.04–1 K. The presence increases by ≈ 1% as reported previously at higher temperatures. Above 0.3 K data for hydrogen‐free copper are good agreement reference equation. At lower there an additional contribution capacity may be associated oxygen impurities.
