Bulk superconductivity at 36 K in La/sub 1. 8/Sr/sub 0. 2/CuO/sub 4/

Journal Article · · Phys. Rev. B: Condens. Matter; (United States)
Cava, van Dover, Batlogg, and Rietman (Phys. Rev. Lett. 58, 408 (1987)) have reported bulk superconductivity at 36 K in La/sub 1.8/Sr/sub 0.2/CuO/sub 4/ which is the highest reported bulk superconducting transition temperature at the writing of this paper. This discovery came in the wake of reported possible high-T/sub c/ superconductivity in a mixture of crystalline phases of the Ba-La-Cu-O system by Bednorz and Muller (Z. Phys. B 64, 189 (1986)). We have also observed superconductivity in samples of La/sub 1.8/Sr/sub 0.2/CuO/sub 4/. The purpose of this paper is to describe briefly the results of our own measurements on this system. We find that our results are in very good agreement with those of Cava et al.
