摘要99Ru Mössbauer effect measurements at 4.2, 23, 30, and 40 K show that the hyperfine magnetic field vanishes near 30 K, lower than the superconducting onset temperature of 45 K in Sr2YRu0.95Cu0.05O6. The data confirm that superconductivity and homogeneous magnetic order coexist. The hyperfine magnetic field measured at 4.2 K is 58.5(0.8) T. The well-resolved set of 18 lines in the 4.2 K measurement enabled a determination of a new value, -0.293(0.005) nm, for the nuclear magnetic moment of the 3/2 state of 99Ru. The isomer shift in this compound was measured to be 0.13(0.01) mm/s and it is consistent with a +5 charge state of Ru.
