Fig. 2: Field-Angle Phase Diagrams at Base Temperature.
From: Orphan high field superconductivity in non-superconducting uranium ditelluride
a Phase diagram of oSCFP at base temperature (approx. 0.5 K), with color indicating total resistance. Circled dark blue regions between 30 and 44o are where the sample resistance falls below the average low field normal state value (~0.31 Ω) and the darkest color, bounded by dot-center diamonds, indicates zero resistance. Superconducting transitions and transitions from the low field normal to field polarized normal states (defined by 50% of the transition) are indicated by purple “-” crossed and red “+” crossed diamonds, respectively. b Comparison of the oSCFP (purple “-” crossed) to SCFP in \({{T}_{c}}_{{{SC}}_{1}}\approx 1.85{K}\) RRR = 64 (- crossed circles) and RRR = 8.8 (- crossed pentagons) crystals between H = 35–55 T and θ = 20–50o. In all cases, the normal state (below Hm) is indicated in white, and the FP normal state (above Orphan UTe2 Hm) in red. Best fit lines for each Hm and Hc2 (dash-dot, short-dot, and solid for RRR = 64, 8.8, and Orphan UTe2 crystals, respectively) are intended as guides to the eye.
