Quasi-one-dimensional spin excitations in the iron pnictide NaFe $_{0.53}$ Cu $_{0.47}$ As

Yifan Wang, David W. Tam, Weiyi Wang +8

Spectroscopic measurements in model one-dimensional (1D) correlated systems offer insights for understanding their two-dimensional counterparts, which include the cuprate and iron…

High-energy magnetic excitations from heavy quasiparticles in CeCu $_{2}$ Si $_{2}$

Yu Song, Weiyi Wang, Chongde Cao +8

Magnetic fluctuations is the leading candidate for pairing in cuprate, iron-based and heavy fermion superconductors. This view is challenged by the recent discovery of nodeless sup…

Spin dynamics in NaFeAs and NaFe $_{0.53}$ Cu $_{0.47}$ As probed by resonant inelastic X-ray scattering

Yu Song, Weiyi Wang, Eugenio Paris +11

The parent compounds of iron-based superconductors are magnetically-ordered bad metals, with superconductivity appearing near a putative magnetic quantum critical point. The presen…

Magnetic order and fluctuations in quasi-two-dimensional planar magnet Sr(Co $_{1 - x}$ Ni $_{x}$ ) $_{2}$ As $_{2}$

Yaofeng Xie, Yu Li, Zhiping Yin +9

We use neutron scattering to investigate spin excitations in Sr(Co $_{1 - x}$ Ni $_{x})_{2}$ As $_{2}$ , which has a $c$ -axis incommensurate helical structure of the two-dimensional (2D) in-pl…

Flat band magnetism and helical magnetic order in Ni-doped SrCo $_{2}$ As $_{2}$

Yu Li, Zhonghao Liu, Zhuang Xu +15

A series of Sr(Co $_{1 - x}$ Ni $_{x}$ ) $_{2}$ As $_{2}$ single crystals was synthesized allowing a comprehensive phase diagram with respect to field, temperature, and chemical substitution to b…

Coexistence of ferromagnetic and stripe antiferromagnetic spin fluctuations in SrCo $_{2}$ As $_{2}$

Yu Li, Zhiping Yin, Zhonghao Liu +16

We use inelastic neutron scattering to study energy and wave vector dependence of spin fluctuations in SrCo $_{2}$ As $_{2}$ , derived from SrFe $_{2 - x}$ Co $_{x}$ As $_{2}$ iron pnictide supercond…
