Abstract

We report the results of Raman scattering measurements which determine the pressure dependence of the inplane exchange coupling constant J in magnetic La₂CuO₄ for pressures between 1bar and 100 kbar. We find that pressure increases the Neel temperature T_N 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.
