Abstract

The effect of hydrostatic pressure on the relaxation rate of crystal-field excitations in the optimally doped high-T_c superconductor La _1.81Sr_0.15Ho_0.04Cu¹⁶O₄ (T_c. = 32.5K) has been investigated by means of inelastic neutron scattering. The temperature T* where the pseudogap opens is found to shift downwards from T* = (61.0 ± 1.3) K (p = 0) to T* = (55.8 ± 1.5) K (p = 0.8GPa) and to T* = (54.1 ± 1.5) K (p = 1.2GPa), i.e., dT*/dp = (-5.9 ± 1.6) K/GPa.
