Metal-insulator transition induced by 16O -18O oxygen isotope exchange in colossal negative magnetoresistance manganites
N. A. Babushkina, L. M. Belova, V. I. Ozhogin +5
The effect of 16O-18O isotope exchange on the electric resistivity was studied for (La(1-y)Pr(y))0.7Ca0.3MnO3 ceramic samples. Depending on y, this mixed perovskite exhibited diffe…

Spin and orbital excitations in magnetic insulators with Jahn-Teller ions
J. van den Brink, W. Stekelenburg, D. I. Khomskii +2
The elementary excitations of a model Hamiltonian that captures the low energy behavior of a simple two-fold degenerate Hubbard Hamiltonian with Hund's rule coupling, is studied. T…
