Research data supporting: A quantum critical line bounds the high field metamagnetic transition surface in UTe2

Contacted and contactless conductivity measurements of the heavy fermion superconductor at high magnetic fields in proximity to its quantum critical line. Contactless conductivity measurements were performed up to 80 T at HZDR Dresden, and to 57 T in Wuhan. Contacted conductivity was measured up to 41 T in NHMFL Florida. Measurements were taken at fixed orientation at various temperatures, and at fixed temperature for variable magnetic field orientation.
