摘要：

The effects of hydrostatic pressure up to 1.3 GPa on the Neel temperature in orthorhombic antiferromagnetic La2CuO4+delta have been investigated using the La-139 NQR method. A positive sign of the pressure derivative, dT(N)/dP = 7.1 K/GPa, as well as an increase in the critical index beta from 0.29 at ambient pressure to 0.33 at 1.3 GPa have been observed. The results were processed using the Green function method.
