TLDR
An automated calorimetry system for measuring heat capacity in the range 1–35 K and is capable of performing rapid, accurate specific heat measurements on very small samples.Abstract:
We describe an automated calorimetry system for measuring heat capacity in the range 1–35 K. The system employs an on‐line computer for signal averaging and data reduction and is capable of performing rapid, accurate specific heat measurements on very small (1–100 mg) samples.read more

TL;DR: In this paper, the authors examined the performance of a thermal-relaxation calorimeter that operates in the temperature range of 1.8-395 K. The accuracy of the PPMS specific heat data is determined by comparing data measured on copper and synthetic sapphire samples with standard literature values.

TL;DR: In this article, a strong dependence of T/sub c/ upon the density of states in the d band indicates that the superconducting electrons are d electrons and the electron interaction parameter, V, of the Bandeen-Cooper-Schrieffer theory is found to be approximately 0.4 ev for all the metals investigated.
