Quantum magnons of the intermediate phase of half-doped manganite oxides

Ivon R. Buitrago, Cecilia I. Ventura, Luis O. Manuel

At half doping, the ground state of three-dimensional manganite perovskite oxides like R $_{1 - x}$ Ca $_{x}$ MnO $_{3}$ , where R is a trivalent ion such as La, Pr, etc, is still unclear. Man…

Spin Excitations in Half-Doped Manganites

Ivon R. Buitrago, C. I. Ventura

We investigate magnetic excitations in half-doped colossal magnetoresistance manganites. In particular, we focus on spin excitations in the CE phase originally proposed by Goodenou…
