一年前，Giauque 和 MacDougall3、de Haas、Wiersma 和 Kramers4 进行了第一个实验，通过某些顺磁物质的绝热退磁产生极低的温度，如 Debye1 和 Giauque2 所建议的。继续我们之前关于磁力方法的实验，我们建造了一个用于研究最低温度区域的装置。由于我们很快将给出一些计算和实验工作的详细报告，因此我们在这里仅提及我们的一些结果。
A YEAR ago the first experiments for producing very low temperatures by adiabatic demagnetisation of certain paramagnetic substances, as suggested by Debye1 and Giauque2, were carried out, by Giauque and MacDougall3, and also by de Haas, Wiersma and Kramers4. Continuing our former experiments5 on the magnetic method, we have constructed an apparatus for investigations in the region of lowest temperatures. As we shall soon give a detailed report of some calculations and experimental work, we will mention here only some of our results.
