Cold and Hot Topics: Probing Materials in Metastable Forms by Mark W Meisel (University of Florida)

Mark W. Meisel

Department of Physics and the National High Magnetic Field Laboratory (or MagLab), MagLab High B/T Facility, University of Florida, Gainesville


The seminar will start with an overview of MagLab High B/T Facility as one-five year cycle (2018-2022) ended and a renewal (2023-2027) was granted for work in the Microkelvin Lab at UF. Next, work being performed in collaboration with the STM-STS team at Šafárik University in Košice, Slovakia, where external magnetic fields up to few tesla may be applied on samples cooled to nominally 5 K, with Fe(II) spin-crossover (SCO) samples [1] provided by the Shatruk Group in Chemistry at Florida State University in Tallahassee, will be presented. Lastly, the development and operation of the High BxT (magnetic field strength times temperature) Facility at UF will be described as part of a project to demonstrate the scalability of inductive heating synthesis/tempering of alloys in high magnetic fields. The results of growing pure Co from a Co-S flux at temperatures above 1000 C while in fields up to 9 T will be described [2].
