제목: Structural phase transitions and charge stripe order in lanthanum copper-oxide superconductors
연사: 백 승 호 박사님 (독일 IFW-Dresden)
일시: 2013. 8. 21(수) 오전 11시 장소: 51동 3층 Creativity Zone (창조존) [1] Baek et al., Phys. Rev. B 85, 184508 (2012) [2] Baek et al., Phys. Rev. B 87, 174505 (2013) [3] Baek et al., (unpublished, in preparation)
초록: In this talk, I will present the nuclear magnetic resonance (NMR) studies [1,2] of La based copper-oxide superconductors (cuprates). Firstly, I will discuss the different nature of the structural phase transitions in La1.8-xEu0.2SrxCuO4 (LESCO) and La2-xSrxCuO4 (LSCO) single crystals [1,2]. Secondly, I will show compelling NMR evidence that charge order is closely connected with spin freezing occurring in 1/8-doped La cuprates and competes with superconductivity [3].
