Abstract

Both ⁶³Cu NQR frequency ν_Q and 1/T₁T were found to decrease under high pressure up to 14kbar, indicating the decrease of hole density at Cu site. The enhancement of T_c under pressure is explained as due to the transfer of hole density from Cu to oxygen, which increases the effective carrier density.
