Awana] We report the effect of Mn ion substitution on the structural, superconducting and magnetic properties of polycrystalline Ru1−x MnxSr2(Eu1.4Ce0.6)Cu2O10−δ system with x=0.0 to 0.50. All the samples crystallizes with tetragonal structure in I4/mmm space group. RuSr2(Eu1.4Ce0.6)Cu2O10−δ (EuRu-1222) is a reported magneto-superconductor with magnetic ordering at 100K and superconductivity occurs at ≅40K. The exact nature of Ru spin magnetic ordering is still being debated and no conclusion has been reached yet. Here, we found the superconducting transition temperature T c=15K from the dc magnetization measurements for undoped sample. It is observed that the superconducting transition temperature decreases with the Mn doping at Ru site. DC magnetic susceptibility measurements exhibited ferromagnetic like transition for all the synthesized samples. It was also observed that the net magnetic moment decreases gradually with Mn doping, though not monotonically. It seems that doping of Mn in EuRu-1222 at Ru site enhance the AFM ordering of Ru spins and suppress the FM component. Our results point out possible coupling between superconductivity and magnetism.
