Description
The transverse magnetoresistance of RuSr2GdCu2O8 is studied as a function of the applied field in several fixed temperatures spanning the superconducting and purely magnetic phases. In low applied fields, the magnetoresistance is positive and results from suppression of superconducting fluctuations. In the high field-high temperature regimes, a spin-disorder contribution to the magnetoresistance is identified. This fact indicates that the magnetic Ru-O2 atomic layers have a conducting character
