Abstract

We have studied magnetostriction in single crystalline La1.85Sr0.15CuO4 using the strain gauge technique in magnetic fields up to 12 T at temperatures 4.2 K < T < 35 K. We have observed giant transverse magnetostriction (of the order of 10(-4) at 4.2 K) for magnetic field B parallel to c and longitudinal magnetostriction (of the order of 10(-5) at 4.2 K) for B perpendicular to c orientation. Pronounced jumps in transverse magnetostriction have been observed in the temperature range between 4.2 K and 8.5 K. Experimental magnetostriction results are compared with magnetization measurements using a vibrating sample magnetometer and gradientometric Hall sensors measurements. The calculations were performed on the basis of a pinning-induced mechanism of magnetostriction. The simple adiabatic theory seems to be insufficient to describe the observed flux instabilities.
