In this paper we report the study of superconductivity and magnetism in Y5−xDyxOs4Ge10 (x=0, 1, 1.75, 2, 2.5, 3, 3.5, 3.75, 4, and 5). Here we observe magnetic ordering at 6.0 K in Dy5Os4Ge10. We find the magnetic ordering temperature decreases linearly as x decreases from 5 to 3 and the superconducting transition temperature decreases as x increases from x=0 to 3 in Y5−xDyxOs4Ge10. We observe the coexistence of superconductivity and magnetism for x=3 from the measurement of the ac susceptibility and resistivity in small applied dc fields. Here we also report upper-critical-field studies of Y5−xDyxOs4Ge10 for x=1.75 and 3.0.
