Aluminum nuclear-demagnetization refrigerator for powerful continuous cooling
Nanomechanical resonators, nanoelectronic systems, amorphous solids, and dark matter searches have each been the subject of recent or proposed experiments at or below 1 mK, but achieving such low cryostat temperatures is challenging. The authors report the performance of an aluminum nuclear demagnetization refrigerator designed to facilitate access to microkelvin temperatures. They found the aluminum refrigerant is well-suited to continuous nuclear demagnetization refrigeration when its natural oxide layer is effectively removed in selected regions. These results will broaden the field of microkelvin physics, accelerating the rate of discovery and increasing its technological potential.
