We have studied EuFe2(As0.7P0.3)(2) by the measurements of x-ray diffraction, electrical resistivity, thermopower, magnetic susceptibility, magnetoresistance, and specific heat. Partial substitution of As with P results in the shrinkage of lattice, which generates chemical pressure to the system. It is found that EuFe2(As0.7P0.3)(2) undergoes a superconducting transition at 26 K, followed by ferromagnetic ordering of Eu2+ moments at 20 K. This finding is the first observation of… CONTINUE READING
