A UNIFYING THEORY OF THE MAGNETIC AND TRANSPORT-PROPERTIES OF LA2-XSRXCUO4

We present a theory of impurity-dominated transport for La2-xSrxCuO4 w hen x less than or similar to 0.05, and use this theory to reanalyze p reviously published data for x = 0.002 (Chen et al., Phys. Rev. Lett. 63 (1989) 2307; Phys. Rev. B 43 (1991)392; 51 (1995) 3671) and x = 0.0 4 (Keimer et al., Phys. Rev. B 46 (1992) 14 034). The starting point o f this theory is identical to one used previously in successfully expl aining the magnetic spin texture for this same compound. Our chiral im purity theory provides the best fit to the experimental data for both doping levels. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
