✦ Synopsis

In order to investigate magnetic interaction and its effect on superconductivity in GdBa2(Cu I xFex )307_v, critical temperature Tc, lattice parameters, d.c. susceptivility, Gd-ESR and Nee] temperature T N are measured. We found that ESR linewidthAHop increases but T N decreases from 2.3 K to 2.0 K with increasing x up to 0.19. This indicates that there exists some magnetic interaction between Gd and Fe atoms even in superconducting state.

Temperature and magnetic field dependences of the thermal conductivity of a GdBa2Cu307-0 high-To superconductor have been measured between 1.5}( and 7.OK. It has been found that the thermal conductivity increases around 2.2K, at which the magnetic orderin~ peak is observed in the specific heat meas

Temperature dependence of the nuclear relaxation rate of both Cu(1) and Cu(2) sites indicates the appearance of the magnetic order without destroying superconductivity in the Fe-doped YBa2Cu307. The impuity-induced antiferromagnetism of Cu moments is verified also by the observation of ~he antiferro
