Field Re-entrant Superconductivity Induced by the Enhancement of Effective Mass in URhGe
Open accessAbstract
High quality single crystals of a ferromagnetic superconductor URhGe were successfully grown. The electrical resistivity was measured for the field along b-axis in the orthorhombic crystal structure in order to study precisely its field re-entrant superconductivity which occurs in the vicinity of the field $H_{\rm R}$, where the easy magnetization switches from $c$ to b-axis. The field re-entrant superconductivity of URhGe is analyzed with special focus on its dependence with the value of residual resistivity $ρ_0$ and the coefficient $A$ of $T^2$ term of the resistivity. The experimental results are well explained by a crude model related with the field dependence of the effective mass $m^\ast$, where the corresponding critical temperature $T_{\mathrm{sc}}(m^\ast)$ and the upper critical field $H_{\rm c2}$ are strongly enhanced. Discussion is made on the interplay between magnetic and superconducting phase diagram as well as the link between $T_{\mathrm{sc}}$ and $A$ in other heavy fermion superconductors.

When the initial Tc boost from enhanced magnetic fluctuations near the metamagnetic field is accounted for, the ordering temperatures of the two phases in URhGe are almost equally affected by disorder, and the reentrant phase appears slightly more fragile.
“However, when the initial Tc boost from enhanced magnetic fluctuations near the metamagnetic field is accounted for, the ordering temperatures of the two phases are almost equally affected by disorder. In fact, the reentrant phase appears to be the slightly more fragile of the two26.”

“While other uranium-containing superconductors, such as URhGe26 and UCoGe1, exhibit field stabilized reentrant superconductivity at specific angles, these phases occur in proximity to ferromagnetic quantum critical points, whereas UTe2 does not magnetically order below 1.4 GPa22.”
From Orphan high field superconductivity in non-superconducting uranium ditelluride (2024) · cites this paper as [26]
The Introduction (p. 1) reports field-reentrant superconductivity in URhGe over a range of field angles around the b-axis. It mentions UCoGe as a ferromagnetic superconductor but does not establish field-reentrant superconductivity in UCoGe. Neither that passage nor the discussion of URhGe’s reorientation field (Conclusion, p. 5) establishes that these phases occur near ferromagnetic quantum critical points. (LLM, conf=0.86)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
