Spin and Lattice Structure of Single Crystal SrFe2As2

Jun Zhao, W. Ratcliff, J. W. Lynn +5

We use neutron scattering to study the spin and lattice structure on single crystals of SrFe2As2, the parent compound of the FeAs based superconductor (Sr,K)Fe2As2. We find that Sr…

Magnons in Ferromagnetic Metallic Manganites

Jiandi Zhang, F. Ye, Hao Sha +3

Ferromagnetic (FM) manganites, a group of likely half-metallic oxides, are of special interest not only because they are a testing ground of the classical doubleexchange interactio…

Spin waves throughout the Brillouin zone and magnetic exchange coupling in ferromagnetic metallic manganites La $_{1 - x}$ Ca $_{x}$ MnO $_{3}$ ( $x = 0.25, 0.30$ )

F. Ye, Pengcheng Dai, J. A. Fernandez-Baca +4

Using time-of-flight and triple-axis inelastic neutron spectroscopy, we determine spin wave excitations throughout the Brillouin zone for ferromagnetic manganites La $_{1 - x}$ Ca $_{x}$ M…

Electronically smectic-like phase in a nearly half-doped manganite

F. Ye, J. A. Fernandez-Baca, Pengcheng Dai +5

We use neutron scattering to study the spin and charge/orbital ordering (CO-OO) in the nearly half-doped perovskite manganite $P r_{0.55} (C a_{0.8} S r_{0.2})_{0.45} M n O_{3}$ (PCSMO). On…
