Heat capacity measurements on a thin ribbon sample of Zr_(0.55)Al_(0.10)Ni_(0.05)Cu_(0.30) glassy alloy and Apiezon N high vacuum grease using a Quantum Design Physical Property Measurement System

摘要

We measured the heat capacity of a thin ribbon sample of Zr_(0.55)Al_(0.10)Ni_(0.05)Cu_(0.30) glassy alloy using a Heat Capacity option of Quantum Design's Physical Property Measurement System (PPMS) between 1.9 K and 310 K. The cut ribbon pieces were piled up to form a block, where each ribbon layer was adhered to one another with Apiezon N grease (ANG), and the heat capacity of the block was measured. In order to obtain the heat capacity of the sample, the heat capacity of ANG was subtracted from the block heat capacity. We report how we measured the heat capacity of a thin ribbon sample, and in this connection, we also reviewed the ANG heat capacity previously reported.
