摘要：

Magnetic susceptibility of single-crystal La2-xSrxCuO4 with various x was measured with a SQUID magnetometer. The susceptibility with magnetic field (H) perpendicular to the CuO2 plane is 1.5 approximately 3 times as large as that with H parallel to the CuO2 plane, whereas they have similar temperature dependence. The field-dependent susceptibility in the vicinity of T(c) was also studied. From these data, T(c)(H), i.e., the field dependence of T(c) for H normal to the CuO2 plane, was determined by a new method. The coherence length at 0 K in the CuO2 plane estimated from T(c)(H) is about 30 angstrom for the samples of x = 0.12, 0.14 and 0.19.
