# Superconductivity in the Ferromagnet URhGe under uniaxial pressure

## TL;DR

Applying uniaxial pressure in URhGe significantly enhances its superconductivity by stimulating triplet pairing mechanisms and affecting magnetic transitions, revealing new insights into pressure-induced superconductivity in ferromagnetic heavy fermion compounds.

## Contribution

This study demonstrates that uniaxial stress along the b-axis enhances superconductivity and modifies magnetic transitions in URhGe, highlighting new mechanisms for pressure-induced superconductivity.

## Key findings

- Uniaxial pressure strongly stimulates superconductivity in URhGe.
- Stress affects the reentrant superconductivity under magnetic field.
- Uniaxial stress lowers the critical field for the transition to the paramagnetic state.

## Abstract

Uniaxial pressure applied in the b crystallographic direction perpendicular to spontaneous magnetization in heavy fermion ferromagnet URhGe strongly stimulates superconductivity in this compound. The phenomenological approach allows point out two mechanisms of superconducting temperature raising. They originates from stimulation by the uniaxial stress both intraband and interband amplitudes of triplet Cooper pairing. The phenomenon of reentrant superconductivity under magnetic field along b-axis is also strongly sensitive to the uniaxial stress in the same direction. The uniaxial stress accelerates suppression the Curie temperature by the transversal magnetic field. The emergence of the first order transition to the paramagnetic state occurs at much lower field than in the absence of uniaxial stress.
