摘要：
Anomalous pressure dependences of the resistance and the superconducting transition temperature T(c) have been observed in La2CuO4 to 17 kbar. With pressure, T(c) first decreases, then takes a minimum at 3 kbar and finally increases at a rate of 0.5 K/kbar. The Neel temperature T(N) decreases with pressure. Some likely origins are briefly discussed for a two-step superconducting transition and negative/positive dT(c)/dP.
