Superconductivity at 32 K in single crystal Rb $_{0.78}$ Fe $_{2}$ Se $_{1.78}$ }

arXiv:1012.5525 · doi:10.1103/PhysRevB.83.060512

Abstract

We successfully grew the high-quality single crystal of Rb $_{0.78}$ Fe $_{2}$ Se $_{1.78}$ , which shows sharp superconducting transition in magnetic susceptibility and electrical resistivity. Resistivity measurements show the onset superconducting transition ( $T_{c}$ ) at 32.1 K and zero resistivity at 30 K. From the low-temperature iso-magnetic-field magnetoresistance, large upper critical field $H_{c2}$ (0) has been estimated as high as 180 T for in-plane field and 59 T for out-of-plane field. The anisotropy $H_{c2}^{ab}$ (0)/ $H_{c2}^{c}$ (0) is around 3.0, right lying between those observed in K $_{x}$ Fe $_{2}$ Se $_{2}$ and Cs $_{x}$ Fe $_{2}$ Se $_{2}$ .
