α- YbAl_{0.986} Fe_{0.014} B_4中\muSR测量弛豫速率的反常温度依赖性
On anomalous temperature dependence of relaxation rate measured by \muSR in α-YbAl_{0.986}Fe_{0.014}B_4
摘要：
最近，MacLaughlin等人在Phys. Rev. B 93，214421（2016）中报道了α- YbAl_{0.986} Fe_{0.014} B_4在$μ$ SR的弛豫速率1/ T_{1}中表现出异常的温度依赖性，并强调这种温度依赖性不能通过基于量子临界价态跃迁（QCVT）的方案来理解而该化合物表现出一系列非费米液体行为，用QCVT理论解释。本文指出，1/ T_{1}的反常温度依赖性可以半定量地理解，假设μ^{+}周围屏蔽的传导电子云的吸引，在Yb离子上产生一个由4f空穴产生的局域磁矩，引起重准粒子间的近藤效应.
英文摘要：
Recently, it was reported by MacLaughlin et al. in Phys. Rev. B 93, 214421 (2016) that α-YbAl_{0.986}Fe_{0.014}B_4 exhibits an anomalous temperature dependence in the relaxation rate 1/T_{1} of $μ$SR, and stressed that such temperature dependence cannot be understood by the scenario based on the quantum critical valence transition (QCVT) while this compound exhibits a series of the non-Fermi liquid behaviors explained by the theory of the QCVT. In this paper, we point out that the anomalous temperature dependence in 1/T_{1} can be understood semi-quantitatively by assuming that the attraction of a screening cloud of conduction electrons about the μ^{+} induces a local magnetic moment arising from a 4f hole on the Yb ion, giving rise to the Kondo effect between heavy quasiparticles.
