Electrical Transport under Pressure in Non-centrosymmetric URhSn

Abstract

We report single crystal growth of the ternary non-centrosymmetric compound URhSn and effect of hydrostatic pressure on its binary transitions occurring at 54 K (T O) and 17 K (T C), respectively. The ground state of URhSn is ferromagnetic, while nature of the phase transition at 54 K is not yet wellestablished. We find that the T O is monotonically suppressed to 37 K at 5.91 GPa, and the anomaly at T C changes to 21.7 K at 3.62 GPa and then to 18 K at 5.91 GPa. Both the transitions show a declining trend with pressure at 5.91 GPa; we expect a complete suppression of T C and T O above 7 GPa. In our electrical resistance measurements a hysteresis revealing a change to first order above a critical pressure is not seen, neither any emergence of a new pressure induced phase is discernible up to 5.91 GPa.
