论文摘要

局部场分布宽度$ΔH\equivσ/γ_μ$的过剩增加($γ_μ= 135.5 \,$ mHz/t是$μ^{+} $的陀螺仪比例),/或/或自发磁场$ h _ {\ h_ {\ h_ {\ rm spon; $μ$ SR(MUON自旋旋转或放松)实验。这些数量的尺寸总体上为1G。 We propose that the increase of the local field distribution $ΔH$ in those compounds, including ions with strong spin-orbit interaction of 5d electrons, such as La in LaNiGa$_2$ or Re in Re$_6$Zr, is possible through the cooperation of the spin-orbit coupling between the quasiparticles and ionic vibrations (phonons) and the conventional quasiparticles-phonon coupling, inducing与螺旋对称性的超导电状态与手性超级自旋电流围绕围绕的旋转旋转p波配对,停止了$μ^{+} $站点。 $ΔH$的大小估计为1G的顺序,与实验观测一致。

The excess increase of the local field distribution width $ΔH\equivσ/γ_μ$ (with $γ_μ=135.5\,$MHz/T being the gyromagnetic ratio of $μ^{+}$), and/or the spontaneous magnetic field $H_{\rm spon}$, have been reported in the superconducting state of a series of compounds more than 10 by $μ$SR (muon spin rotation or relaxation) experiment. Sizes of these quantities are of the order of 1G on the whole. We propose that the increase of the local field distribution $ΔH$ in those compounds, including ions with strong spin-orbit interaction of 5d electrons, such as La in LaNiGa$_2$ or Re in Re$_6$Zr, is possible through the cooperation of the spin-orbit coupling between the quasiparticles and ionic vibrations (phonons) and the conventional quasiparticles-phonon coupling, inducing the spin-triplet p-wave pairing with helical symmetry breaking superconducting state with chiral super spin current around stopped $μ^{+}$ site. The size of $ΔH$ is estimated as of the order of 1G, in consistent with experimental observations.
