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

· Phys. Rev. Lett.; (United States)
We report the results of resistivity and magnetic susceptibility measurements in La/sub 2-//sub x/Sr/sub x/CuO/sub 4/ for xless than or equal to0.3. The x = 0.2 sample shows a superconducting transition at 36.2 K with a width of 1.4 K. The associated dc diamagnetic susceptibility (Meissner effect) is a large fraction (60%--70%) of the ideal value. We estimate the density of states from critical-field and resistivity data and suggest, by analogy to BaPb/sub 1-//sub x/Bi/sub x/O/sub 3/, that conventional phonon-mediated superconductivity can account for the high T/sub c/ in this class of materials.
