TEMPERATURE-DEPENDENT ANISOTROPY IN LA1.86SR0.14CUO4

Based on the scaling rule: R(T, H, theta) = R(T, h), where h = H(sin(2 ) theta + cos(2) theta/gamma(2))(1/2) and theta is field angle with re spect to the ab-plane, the scaling approach is performed to examine th e c-axis resistances of single crystalline La1.86Sr0.14CuO4 as functio ns of field and its orientation at different temperatures. The anisotr opy parameter gamma of the system is extracted hom the scaling approac h, but shows an unusual temperature-dependent behavior, which is not e xpected by conventional theory. A phenomenological explanation of this temperature dependence is presented.
