Orbital-selective spin waves in detwinned NaFeAs
David W. Tam, Zhiping Yin, Yaofeng Xie +6
The existence of orbital-dependent electronic correlations has been recognized as an essential ingredient to describe the physics of iron-based superconductors. NaFeAs, a parent co…
Anisotropic effect of a magnetic field on the neutron spin resonance in FeSe
Tong Chen, Youzhe Chen, David W. Tam +9
We use inelastic neutron scattering to study the effect of a magnetic field on the neutron spin resonance (Er = 3.6 meV) of superconducting FeSe (Tc = 9 K). While a field aligned a…
Uniaxial -axis pressure effects on underdoped BaFe(AsP) superconductor
Ding Hu, David W. Tam, Wenliang Zhang +5
The optimal superconductivity ( K) in BaFe(AsP) can be reached when the coupled antiferromagnetic (AF) order () and orthorhombic lattice d…
Plaquette instability competing with bicollinear ground state in detwinned FeTe
David W. Tam, Hsin-Hua Lai, Jin Hu +10
We use inelastic neutron scattering to show that long-range spin waves arising from the static bicollinear antiferromagnetic (AF) order in FeTe, which have twofold rotational symme…
Impact of the first order antiferromagnetic phase transition on the paramagnetic spin excitations and nematic phase of SrFeAs
David W. Tam, Weiyi Wang, Li Zhang +7
Understanding the nature of the electronic nematic phase in iron pnictide superconductors is important for elucidating its impact on high-temperature superconductivity. Here we use…
Experimental signatures of a three-dimensional quantum spin liquid in effective spin-1/2 Ce2Zr2O7 pyrochlore
Bin Gao, Tong Chen, David W. Tam +20
A quantum spin liquid (QSL) is a state of matter where unpaired electrons' spins in a solid are quantum entangled, but do not show magnetic order in the zero-temperature limit. Bec…
