Evidence of unconventional low-frequency dynamics in the normal phase of Ba(Fe1-xRhx)2As2 iron-based supercondutors
L. Bossoni, P. Carretta, W. P. Halperin +4
This work presents 75As NMR spin echo decay rate (1/T2) measurements in Ba(Fe1-xRhx)2As2 superconductors, for 0.041 < x < 0.094. It is shown that 1/T2 increases upon cooling, in th…
Microscopic coexistence of a two-component incommensurate spin density wave with superconductivity in underdoped NaFeCoAs
Sangwon Oh, A. M. Mounce, Jeongseop A. Lee +6
We have performed As and Na nuclear magnetic resonance (NMR) measurements on a single crystal of NaFeCoAs and found microscopic coexistence of s…
Absence of static orbital current magnetism at the apical oxygen site in HgBaCuO from NMR
A. M. Mounce, Sangwon Oh, Jeongseop A. Lee +9
The simple structure of HgBaCuO (Hg1201) is ideal among cuprates for study of the pseudogap phase as a broken symmetry state. We have performed O nuclear magneti…
Magnetic field dependence of spin-lattice relaxation in the s state of BaKFeAs
Sangwon Oh, A. M. Mounce, W. P. Halperin +4
The spatially averaged density of states, <N(0)>, of an unconventional d-wave superconductor is magnetic field dependent, proportional to , owing to the Doppler shift of q…
Spin-Density Wave near the Vortex Cores of BiSrCaCuO
A. M. Mounce, S. Oh, S. Mukhopadhyay +6
Competition with magnetism is at the heart of high temperature superconductivity, most intensely felt near a vortex core. To investigate vortex magnetism we have developed a spatia…
Charge Induced Vortex Lattice Instability
A. M. Mounce, S. Oh, S. Mukhopadhyay +6
It has been predicted that superconducting vortices should be electrically charged and that this effect is particularly enhanced for, high temperature superconductors.\cite{kho95,b…
Magnetic Impurities in the Pnictide Superconductor BaKFeAs
Sutirtha Mukhopadhyay, Sangwon Oh, A M Mounce +7
NMR measurements have been performed on single crystals of BaKFeAs (x = 0, 0.45) and CaFeAs grown from Sn flux. The Ba-based pnictide crystals contain…
