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…
Nanoscale Phase Separation in Colossal Magnetoresistance Materials: A Lesson for the Cuprates?
Elbio Dagotto, Jan Burgy, Adriana Moreo
A recent vast experimental and theoretical effort in manganites has shown that the colossal magnetoresistance effect can be understood based on the competition of charge-ordered an…
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…
