Spin/Orbital Pattern-Dependent Polaron Absorption in Nd(1-x)Sr(x)MnO3
M. W. Kim, J. H. Jung, K. H. Kim +4
We investigated optical properties of Nd(1-x)Sr(x)MnO3 (x= 0.40, 0.50, 0.55, and 0.65) single crystals. In the spin/orbital disordered state, their conductivity spectra look quite…
Magnon scattering processes and low temperature resistivity in CMR manganites
N. Furukawa, Y. Shimomura, T. Akimoto +1
Low temperature resistivity of CMR manganites is investigated. At the ground state, conduction electrons are perfectly spin polarized, which is called half-metallic. From one-magno…
Independent freezing of charge and spin dynamics in La1.5Sr0.5CoO4
I. A. Zaliznyak, J. P. Hill, J. M. Tranquada +2
We present elastic and quasielastic neutron scattering measurements characterizing peculiar short-range charge-orbital and spin order in the layered perovskite material La1.5Sr0.5C…
Spin Dynamical Properties of the Layered Perovskite La1.2Sr1.8Mn2O7
H. Fujioka, M. Kubota, K. Hirota +3
Inelastic neutron-scattering measurements were performed on a single crystal of the layered colossal magnetoresistance (CMR) material La1.2Sr1.8Mn2O7 (Tc ~ 120K). We found that the…
Neutron Scattering Studies on Magnetic Structure of the Double-Layered Manganite La_{2-2x}Sr_{1+2x}Mn_2O_7 ()
M. Kubota, H. Fujioka, K. Ohoyama +4
Systematic powder diffraction studies have been carried out to establish the magnetic phase diagram of La_{2-2x}Sr_{1+2x}Mn_2O_7 (LSMO327) in a wide hall concentration range ($0.30…
Interplay of the CE-type charge ordering and the A-type spin ordering in a half-doped bilayer manganite La{1}Sr{2}Mn{2}O{7}
M. Kubota, H. Yoshizawa, Y. Moritomo +3
We demonstrate that the half-doped bilayer manganite La_{1}Sr_{2}Mn_{2}O_{7} exhibits CE-type charge-ordered and spin-ordered states below K and below $T_{N}^{C…
