✦ Synopsis

Two-stage nuclear demagnetization has been performed using PrCu6 and Cu as coolants. The Cu nuclear stage reached temperatures as low as 10 izK with a rate of temperature rise of less than a few IxK/h. The corresponding conduction electron temperature is estimated to be less than 50 I~K. A nuclear orientation thermometer of A154Mn has been successfully used to measure temperatures down to 10 ~K:
