Tuning the interplay between nematicity and spin fluctuations in NaLiFeAs superconductors
S. H. Baek, Dilip Bhoi, Woohyun Nam +4
Strong interplay of spin and charge/orbital degrees of freedom is the fundamental characteristic of the iron-based superconductors (FeSCs), which leads to the emergence of a nemati…
JLab Measurements of the 3He Form Factors at Large Momentum Transfers
A. Camsonne, A. T. Katramatou, M. Olson +66
The charge and magnetic form factors, FC and FM, of 3He have been extracted in the kinematic range 25 fm-2 < Q2 < 61 fm-2 from elastic electron scattering by detecting 3He recoil n…
Enhanced Upper Critical Fields in a New Quasi-one-dimensional Superconductor Nb2PdxSe5
Seunghyun Khim, Bumsung Lee, Ki-Young Choi +9
We report a discovery of superconductivity with Tc = 5.5 K in Nb2PdxSe5, in which one-dimensional (1D) Nb-Se chains existing along the b-direction hybridize each other to form the…
JLab Measurement of the He Charge Form Factor at Large Momentum Transfers
A. Camsonne, A. T. Katramatou, M. Olson +66
The charge form factor of $^$4He has been extracted in the range 29 fm fm from elastic electron scattering, detecting He nuclei and electrons in…
Orbital selective Fermi surface shifts and mechanism of high T superconductivity in correlated AFeAs (A=Li,Na)
Geunsik Lee, Hyo Seok Ji, Yeongkwan Kim +9
Based on the dynamical mean field theory (DMFT) and angle resolved photoemission spectroscopy (ARPES), we have investigated the mechanism of high superconductivity in stoichi…
Probing the Order Parameter of Superconducting LiFeAs using Pb/LiFeAs and Au/LiFeAs Point-Contact Spectroscopy
Xiaohang Zhang, Bumsung Lee, Seunghyun Khim +3
We have fabricated c-axis point contact junctions between high-quality LiFeAs single crystals and Pb or Au tips in order to study the nature of the superconducting order parameter…
Magnetic field - dependent Labusch parameter in LiFeAs superconductor from Campbell penetration depth
Plengchart Prommapan, Makariy A. Tanatar, Bumsung Lee +3
A true critical current density, , as opposite to commonly measured relaxed persistent (Bean) current, , was extracted from the Campbell penetration depth, $λ_{C}(T,H…
Low Q^2 measurements of the proton form factor ratio
G. Ron, X. Zhan, J. Glister +84
We present an updated extraction of the proton electromagnetic form factor ratio, mu_p G_E/G_M, at low Q^2. The form factors are sensitive to the spatial distribution of the proton…
Pauli-limiting effects in the upper critical fields of a clean LiFeAs single crystal
Seunghyun Khim, Bumsung Lee, Jae Wook Kim +3
We have investigated the temperature-dependence of the upper critical field Hc2(T) in a LiFeAs single crystal by direct measurements of resistivity under static magnetic fields up…
Single crystal growth and superconducting properties of LiFeAs
Bumsung Lee, Seunghyun Khim, Jung Soo Kim +2
We report the successful growth of high quality single crystals of LiFeAs with lateral sizes up to 5 x 5 mm2 by the Sn-flux method. Electrical resistivity studies reveal that the s…
Realization of giant magnetoelectricity in helimagnets
Sae Hwan Chun, Yi Sheng Chai, Yoon Seok Oh +9
We show that low field magnetoelectric (ME) properties of helimagnets Ba0.5Sr1.5Zn2(Fe1-xAlx)12O22 can be efficiently tailored by Al-substitution level. As x increases, the critica…
The Proton Elastic Form Factor Ratio at Low Momentum Transfer
G. Ron, J. Glister, B. Lee
High precision measurements of the proton elastic form factor ratio have been made at four-momentum transfers, Q^2, between 0.2 and 0.5 GeV^2. The new data, while consistent with p…
