    Abstract

    We have measured the upper critical field of (La.925Ba.075)2CuO4-y in the range from 0 to 30 Tesla in the hybrid magnet at the Francis Bitter National Magnet Lab. The resistive transition in zero field onsets above 3 OK, with .9Rn at 29K, .1Rn at 27K and 0 below 24K (Rn = R(3 4K). Following the II-T curves for different fractions of Rn we find substantial differences in the temperature dependence of the apparent critical field. However, for (H,T)=.9Rn there is good agreement with simple pairbreaking behavior with an extrapolated Hc2(0) of 46 Tesla. At 4K there is no measurable resistance to 30 Tesla.
