Magnetic and electronic structures of superconducting RuSr${}_2$GdCu${}_2$O${}_8$

K. Nakamura, K. T. Park, A. J. Freeman +1

The coexistence of ferromagnetism and superconductivity in RuSr${}_2$GdCu${}_2$O${}_8$ was reported both from experiments (by Tallon et. al.) and first-principles calculations (by Picket…
