아래와 같이 세미나를 개최하오니 많이 참석해 주시기 바랍니다. 아 래 제목: NQR/NMR study on a single crystal of LiFeAs 연사: 백 승 호 박사 (Leipniz Institute, IFW-Dresden) 일시: 2010년 7월 28일(수) 오후 2:00 장소: 물리학과 세미나실 (31355호실) 초록: I present the results of NMR/NQR study in a stoichiometric Fe-based pnictide, LiFeAs. LiFeAs shows the superconductivity at 18 K without chemical doping or pressure unlike other pnictides. The absence of the magnetism in this compound may raise a question about the seemingly intimate relationship between the magnetism and the superconductivity. In order to study the superconductivity and its origin in the microscopic level, we performed NMR and NQR measurements. Our NQR spectra in zero field and NMR spectra at 7 T exhibit narrow linewidths, supporting high-quality single crystal which allows the precise measurements of the Knight shift or the spin susceptibility as a function of temperature and angle. Together with the spin-lattice relaxation rates by both NQR and NMR, I will discuss the unusual spin states both in the normal and in the superconducting states. The discussion will be given in the general context of iron pnictide superconductors. 86749462238674946223
