Crystal Electric Field (CEF) Effect in Ce2Zr2O7 Pyrochlore
In recent years, there has been a great interest in quantum spin liquid (QSL). The QSL state is characterized by no conventional order parameter associated with a broken... -
Temperature Dependence of the Magnetic Excitations in Ni-doped NaFeAs
In a recent work by Jun Zhao's group [Nature Communications 7, 12182 (2016)], they show that FeSe exhibits both stripe (1,0) and Néel (1,1) antiferromagnetic order, with the... -
Magnetic interactions in honeycomb iridates Na2IrO3
We propose to study the magnetic excitation spectrum of Na2IrO3 with inelastic neutron scattering. Na2IrO3 is a promising candidate to realize Kitaev interaction. By mapping out... -
Is magnetic frustration behind the tetragonal-to-orthorhombic transition in t...
It has been argued that the tetragonal-to-orthorhombic structural transition found in all the parent phases of the Fe-pnictide superconductors is driven by frustration, and... -
Is there electronic nematic order in Fe pnictides?
The concept of an electronic nematic, in which the electronic wavefunctions have different symmetry to the crystal structure, has been proposed to explain several unusual... -
Inelastic neutron scattering study on the one dimensional magnetic systems Ba...
Most of the one dimensional spin chain compounds are antiferromagnetic with a rich magnetic phase diagram due to the magnetic frustration. We have synthesized Ba3CrS5 and... -
High energy spin excitations detwinned SrFe2As2 single crystals
We are proposing to use inelastic neutron scattering to map out the spin excitation in 100% detwinned SrFe2As2 single crystals. We want to sort out how the anisotropic magnetic... -
Spin excitations in LiFeAs, a stoichiometric ferropnictide superconductor at ...
We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is...
