AI Technical Summary
Existing technologies cannot simultaneously achieve magnetic measurements under extremely low temperatures (0.3 to 1.8 K) and ultra-high pressures (20 to 60 GPa), and a testing device that is easy to operate and compatible with commercial magnetic measurement systems has not yet emerged.
An ultra-miniature diamond anvil cell device was designed, including an anvil assembly, a pressurizing assembly, and a connector. It adopts a modular structure and achieves pressurization through reverse thread tightening, which simplifies the complex structure of traditional DACs. The anvil assembly has a diameter of less than 6 mm and a weight of no more than 3 g, and is compatible with MPMS systems.
It enables magnetic measurement under extremely low temperature and ultra-high pressure conditions, filling the gap in existing technology and providing a key means for the study of quantum phenomena such as heavy fermion superconductivity at extremely low temperature and high pressure. It is also easy to operate, low in cost, and compatible with commercial magnetic measurement systems.
