The crystalline electric field as a probe for long range antiferromagnetic order and superconductivity in CeFeAsO$_{1-x}$F$_x$ (2008)

Chi, Songxue, Adroja, D. T., Guidi, T., Bewley, R., Li, Shiliang, Zhao, Jun, ...

We use inelastic neutron scattering to study the crystalline electric field (CEF) excitations of Ce$^{3+}$ in CeFeAsO$_{1-x}$F$_{x}$($x=0,0.16$). For nonsuperconducting CeFeAsO, the Ce CEF levels...

Chi, Songxue, Dai, Pengcheng, Barnes, T., Kang, H. J., Lynn, J. W., Bewley, R., ...

We use neutron scattering to study the Pr$^{3+}$ crystalline electric field (CEF) excitations in the filled skutterudite PrOs$_4$As$_{12}$. By comparing the observed levels and their strengths under...

Effect of antiferromagnetic spin correlations on lattice distortion and charge ordering in Pr$_{0.5}$Ca$_{1.5}$MnO$_{4}$ (2007)

Chi, Songxue, Ye, F., Dai, Pengcheng, Fernandez-Baca, J. A., Huang, Q., Lynn, J. W., ...

We use neutron scattering to study the lattice and magnetic structure of the layered half-doped manganite Pr$_{0.5}$Ca$_{1.5}$MnO$_4$. On cooling from high temperature, the system first becomes...

Resonance in the electron-doped high-Tc superconductor Pr0.88LaCe0.12CuO(4-delta) (2006)

Wilson, Stephen D., Dai, Pengcheng, Li, Shiliang, Chi, Songxue, Kang, H. J., Lynn, J. W.

In conventional superconductors, the interaction that pairs the electrons to form the superconducting state is mediated by lattice vibrations (phonons). In high-transition temperature (high-Tc)...
