^<27>Al NMR/NQR Studies of YbAl_3C_3(Condensed matter: electronic structure and electrical, magnetic, and optical properties)

概要
- 論文の詳細を見る
The phase transition at T^*=80K in YbAl_3C_3 has been studied by ^<27>Al nuclear quadrupole resonance (NQR) measurement and nuclear magnetic resonance (NMR) measurement up to 30T. The NQR and NMR spectra reveal clear anomalies just below T^*, which provides the first microscopic evidence for symmetry lowering in the low-temperature phase below T^*. The transition is characterized by marked changes in the ^<27>Al-NQR frequencies v_Q's without significant changes in the lattice parameters. The field dependence of the transition is also investigated. The NMR line exhibits field-induced rapid broadening below T^*, which almost vanishes in zero field. Moreover, we found that T^* increases by 10K at 30. These unique magnetic properties are consistent with the scheme that the microscopic mechanism underlying the phase transition involves Yb-4f electrons rather than the scheme of a simple structural phase transition.
