Abstract

We have measured the temperature dependence of the resistance for a

{La}_{2} Cu O_{4 + δ}

single crystal at pressures from 1 bar to 18 kbar. The effects of pressure on the antiferromagnetic transition temperature

T_{N}

and the superconducting transition temperature

T_{c}

are compared to those of oxygen doping.
