Unveiling New Magnetic Phases of Undoped and Doped Manganites
Takashi Hotta, Mohammad Moraghebi, Adrian Feiguin +3
Novel ground-state spin structures in undoped and lightly-doped manganites are here investigated based on the orbital-degenerate double-exchange model, by using mean-field and nume…
A possible path to a new class of ferromagnetic and half metallic ferromagnetic materials
I. S. Elfimov, S. Yunoki, G. A. Sawatzky
We introduce a path to a possibly new class of magnetic materials whose properties are determined entirely by the presence of a low concentration of specific point defects in their…
Optical Conductivity and Resistivity of a Hole Doped Spin-Fermion Model for Cuprates
M. Morgaghebi, S. Yunoki, A. Moreo
The optical conductivity and Drude weight of a Spin-Fermion model for cuprates are studied as a function of electronic density and temperature. This model develops stripes and robu…
