摘要：
A characterization of the magnetic superconductor RuSr2GdCu2O8 through resistance measurements as a function of temperature and magnetic field up to 9 T is presented. The intragrain transition shows a two-step behavior with the increase in field, which is explained as a consequence of the effects of a spin-flop transition of the Ru-sub-lattice on the boundaries connecting intragranular structural domains.
