摘要：

The anisotropic pressure dependence of the resistivity of YBa2Cu4O8 has been determined for the two plane directions a and b. The resistivity in a direction, rho(a), reflecting CuO2 planes, revealed a strong pressure dependence d lnp(a)/dp=13x10(-3) kbar(-1). In the stiffer b direction with two conduction channels, along CuO chains and CuO2 planes, a smaller decrease upon pressure but the strongest change with respect to the lattice contraction was found. The pressure dependence observed can be explained by a charge transfer from chains to planes.
