Abstract
The superconducting (Formula presented) materials are also magnetically ordered at (Formula presented)≫:(Formula presented) ((Formula presented)∼42, 32 and (Formula presented)∼180, 122 K for R=Gd and Eu, respectively). Magnetic susceptibility and Mössbauer spectroscopy show that superconductivity is confined to the (Formula presented) planes, whereas magnetism is due to the Ru sublattice. Scanning-tunneling-spectroscopy measurements reveal a superconducting gap structure for the whole sample, indicating that the materials are of single phase, which simultaneously manifest both superconductivity and magnetism.
