Abstract

Vector magnetization measurements in La1.85 Sr0.15 Cu O4 under a steady field H tilted relative to the ab plane show that the induction B rotates toward H with time. The rate of rotation as a function of temperature exhibits two peaks separated by a dip around 12 K. Measurements of the remnant induction show that for temperatures below ∼12 K, B rotates towards the c axis, whereas for temperatures above ∼12 K, B rotates towards the ab planes. We argue that these data are consistent with a two-dimensional and a three-dimensional behavior below and above the dimensional crossover temperature, ∼12 K, respectively.
