| Research Abstract |
For the" superclean" single crystals of Sr_2RuO_4 and UPt_3 with spin-triplet superconductivity, tiny flux-jumps successively appear in the hysteretic magnetization around zero-field at low temperatures, unlike to the case of" superclean" single crystals in spin singlet superconductors. This suggests that the tiny flux-jumps, which successively appear in the hysteretic magnetization around zero-field, are characteristic of the spin-triplet superconductors with mobile d-domain which is related to the internal degree of freedom in the order parameter in the spin-triplet superconductors.
