Order of Degrees of Freedom in Underdoped Manganites

arXiv:cond-mat/0608348

Abstract

Using the degenerate double exchange Hamiltonian with on-site Coulomb interactions we show how the spin, charge, and orbital state degrees of freedom vary in La_{1-x}Ca_{x}MnO_{3} for dopings in between x=4 and x=5. With the ordered configuration of the system we investigate the band structure for different values of the doping.
