Abstract

We report the results of Raman scattering measurements which determine the pressure dependence of the in-plane exchange coupling constant J in magnetic La2CuO4 for pressure between 1bar and 100 kbar. We find that pressure increases the Neel temperature TN much more rapidly than J. This result together with the theory for a quasi two-dimensional magnetic system then suggests that the interplanar exchange coupling decreases with pressure.
