The High B/T (magnetic field / temperature) Facility meets the needs of users who wish to conduct experiments in high magnetic fields (up to 16.5 tesla) and at very low temperatures (down to 0.5 mK) simultaneously. Located at the University of Florida in Gainesville, it is operated as part of the Physics Department's Microkelvin Laboratory. Faculty members in the facility work with users in the design of experiments where needed.
"The experiment … is my first time to collaborate with NHFML researchers and get machine time to perform AC susceptibility measurements at ultra-low temperatures. In this program, everything was going on well and we have not met any problems. The experimental results are also perfect. We hope to be able to have more chance to perform nice measurements in NHFML facilities."

Incipient Formation of Wigner Crystal in Strongly Interacting 2D Holes
19 January 2021
This highlight reports on the still poorly understood transition to an electron crystalline state (the Wigner crystal) in a two-dimensional system at extremely low densities, observable at low temperatures as a function of magnetic field. This experiment finds a surprising stabilization of the Wigner crystal arising from magnetic-field-induced spin alignment. Such electrically-delicate samples require the ultra-low-noise environment and experimental techniques available at the High B/T facility.
