Nano-magnetic droplets and implications to orbital ordering in La1-xSrxCoO3

D. Phelan, Despina Louca, S. Rosenkranz +9

Inelastic cold neutron scattering on LaCoO3 provided evidence for a distinct low energy excitation at 0.6 meV coincident with the thermally induced magnetic transition. Coexisting…

Quasiparticle-like peaks, kinks, and electron-phonon coupling at the ( $π$ ,0) regions in the CMR oxide La $_{2 - 2 x}$ Sr $_{1 + 2 x}$ Mn $_{2}$ O $_{7}$

Z. Sun, Y. -D. Chuang, A. V. Fedorov +11

Using Angle-Resolved Photoemission (ARPES), we present the first observation of sharp quasiparticle-like peaks in a CMR manganite. We focus on the ( $π$ ,0) regions of k-space and st…

Magnetodielectric consequences of phase separation in the colossal magnetoresistance manganite Pr0.7Ca0.3MnO3

R. S. Freitas, J. F. Mitchell, P. Schiffer

We have studied the low-frequency dielectric properties of the phase-separated manganite Pr0.7Ca0.3MnO3 as a function of applied magnetic field in the low temperature phase-separat…

Extracting d-orbital occupancy from magnetic Compton scattering in bilayer manganites

B. Barbiellini, P. E. Mijnarends, S. Kaprzyk +4

We consider the shape of the magnetic Compton profile (MCP), $J_{ma g} (p_{z})$ , in La $_{1.2}$ Sr $_{1.8}$ Mn $_{2}$ O $_{7}$ for momentum transfer $p_{z}$ along the [110] direction and the associ…

Magnetic momentum density, Fermi surface and directional magnetic Compton profiles in LaSr $_{2}$ Mn $_{2}$ O $_{7}$ and La $_{1.2}$ Sr $_{1.8}$ Mn $_{2}$ O $_{7}$

P. E. Mijnarends, S. Kaprzyk, B. Barbiellini +4

We have carried out first principles, all-electron computations of the magnetic momentum density $ρ_{ma g} (p)$ and magnetic Compton profiles (MCPs) for momentum transfer a…
