Order of Degrees of Freedom in Underdoped Manganites
E. R. Sanchez Guajardo
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}…

Quantum Ferroelectric Magnets in Underdoped Manganites
E. R. Sanchez Guajardo
Using the degenerate double exchange Hamiltonian with on-site Coulomb interactions we show that there is an instability towards the displacement of the manganese ion in La_{1-x}Ca_…
