(DURIP) LOW-TEMPERATURE RECONDENSING MAGNET SYSTEM WITH DILUTION REFRIGERATOR INSERT FOR RESEARCH IN ELECTRONIC PROPERTIES NEAR QUANTUM PHASE TRANSITIONS AND IN TOPOLOGICAL MATERIALS
Abstract
The PIs propose acquiring a 9 Tesla cryogen-free magnet system with adiabatic demagnetization refrigerator and dilution refrigerator inserts. The instrument will enable new and enhanced characterization of the materials synthesized as part of both PIs’ AFOSR programs. In particular, the new equipment will enable measurement of magnetotransport, heat capacity and susceptibility properties down to 50 mK – a regime of critical interest in order to address the properties of metals proximate to quantum phase transitions and to probe two dimensional topological ground states and emergent metallic states at oxide interfaces. In addition, the instrument will substantially reduce helium costs, while also increasing the amount of measurement time available for both PIs’ AFOSR projects, significantly increasing materials characterization through-put. The anticipated lifetime for the instrument is at least 20 years, and most likely considerably longer. Acquisition of this system will therefore have a prolonged impact on the research capabilities of both PIs, providing access to ultra-low temperatures for sample characterization for decades to come.
