M. Hackel,H. Kosina,S. Selberherrmagnetic field (colossal magnetoresistance or CMR), has been shown to arise from a strong charge-lattice coupling mediated by the Jahn-Teller distortion of Mn. -ions. We review recent structural work on conventional A.A ’.MnO. and bi-layered A.A’.Mn.O. manganite perovskites, that shows that this cou

Modeling Nano-Structure Devices,ring. We show that these systems evolve, at low temperature, from a canted antiferromagnetic state (CAF) towards an insulating ferromagnetic state (FI), approaching the metallic transition (.. =0.22 and ... 0.17). For .. and ... 0.125, we observe magnetic elastic diffuse scattering characteristic of

D. Schipanski,Z. Gergintschew,J. Kositzatypes of phase inhomogeneities directly relevant to the colossal magnetoresistance (CMR) are discussed. The first type involves micrometer-scale coexistence of structurally and electronically different phases. We present extensive experimental data for a prototypical system exhibiting such a phase c

A recent example, subsequent to that of cuprate superconductors, is of rare earth manganites doped with alkaline earths, namely ......, which exhibit colossal magnetoresistance, metal insulator transition and many other poorly understood phenomena. Here we show that the strong Jahn Teller coupli
