Critical Behavior of the SDW Transition in Underdoped Ba(Fe1-xCox)2As2 (x <=0.05): 75As NMR Investigation
F. L. Ning, M. Fu, D. A. Torchetti +5
We investigate the nature of the SDW (Spin Density Wave) transition in the underdoped regime of an iron-based high Tc superconductor Ba(Fe1-xCox)2As2 by 75As NMR, with primary focu…
Evolution of Quantum Fluctuations Near the Quantum Critical Point of the Transverse Field Ising Chain System CoNbO
A. W. Kinross, M. Fu, T. J. Munsie +4
The transverse field Ising chain (TFIC) model is ideally suited for testing the fundamental ideas of quantum phase transitions, because its well-known ground state can be ext…
Local Spin Susceptibility of the S=1/2 Kagome Lattice in ZnCu3(OD)6Cl2
T. Imai, M. Fu, T. H. Han +1
We report single-crystal 2-D NMR investigation of the nearly ideal spin S=1/2 kagome lattice ZnCu3(OD)6Cl2. We successfully identify 2-D NMR signals originating from the nearest-ne…
Evidence for a Gapped Spin-Liquid Ground State in a Kagome Heisenberg Antiferromagnet
M. Fu, T. Imai, T. -H. Han +1
The kagome Heisenberg antiferromagnet is a leading candidate in the search for a spin system with a quantum spin-liquid ground state. The nature of its ground state remains a matte…
NMR Search for the Spin Nematic State in LaFeAsO Single Crystal
M. Fu, D. A. Torchetti, T. Imai +3
We report a 75-As single crystal NMR investigation of LaFeAsO, the parent phase of a pnictide high Tc superconductor. We demonstrate that spin dynamics develop a strong two-fold an…
Characterization of the first prototype CMOS pixel sensor developed for the CEPC vertex detector
L. J. Chen, H. B. Zhu, X. C. Ai +14
Purpose: CMOS pixel sensors have become extremely attractive for future high performance tracking devices. Initial R\&D work has been conducted for the vertex detector for the prop…
77Se NMR Investigation of the K(x)Fe(2-y)Se(2) High Tc Superconductor (Tc=33K)
D. A. Torchetti, M. Fu, D. C. Christensen +4
We report a comprehensive 77Se NMR study of the structural, magnetic, and superconducting properties of a single crystalline sample of the newly discovered FeSe-based high temperat…
