The superconducting R 1.4 Ce 0.6 RuSr 2 Cu 2 O 10-Ξ΄ (R = Sm, Eu and Gd) with T c βΌ 28, 32 and 42 K are also magnetically ordered at T N βΌ 220, 122 and 180 K, respectively, thus, T N T c . This is in contrast to intermetallic magnetic superconductors (such as RNi 2 B 2 C) in which T c > T N . Magneti
