A study of the coexistence of superconductivity and ferromagnetism in magnetic superconductor RuSr2YCu2O8 (RuY1212) was performed. The analysis was performed using Ru- and Cu-NMR studies. The ordered RuO2 plane showed the existence of ferromagnetic (FM) component below a Curie temperature of 150 K. A decrease of the nuclear spin-lattice relaxation state was observed just below the onset temperature of superconductivity. Motion of self-induced vortices originated from fluctuations of the FM component induced resistivity in RuY1212.
