摘要: We report a study of the magnetization density in mixed state unconventional superconductor ${\mathrm{Sr}}_{2}{\mathrm{RuO}}_{4}$. On entering superconducting we find no change magnitude or distribution induced moment for magnetic field 1 T applied within Ru ${\mathrm{O}}_{2}$ planes. Our results are consistent with spin-triplet Cooper pairing spins lying basal plane. This is contrast similar experiments performed on conventional and high- ${T}_{c}$ superconductors.
