Electrical transport and percolation in magnetoresistive manganite / insulating oxide composites: case of La0.7Ca0.3MnO3 / Mn3O4
B. Vertruyen, R. Cloots, M. Ausloos +2
We report the results of electrical resistivity measurements carried out on well-sintered La0.7Ca0.3MnO3 / Mn3O4 composite samples with almost constant composition of the magnetore…

Unusual thermoelectric behavior of packed crystalline granular metals
M. Ausloos, M. Pekala, J. Latuch +4
Loosely packed granular materials are intensively studied nowadays. Electrical and thermal transport properties should reflect the granular structure as well as intrinsic propertie…

AC magnetic behavior of large grain magneto-resistive La0.78Ca0.22Mn0.90Ox materials
Ph. Vanderbemden, B. Vertruyen, A. Rulmont +3
We report a detailed set of AC magnetic measurements carried out on bulk large grain La-Ca-Mn-O samples extracted from a floating zone method-grown rod. Three samples with $La_{0.7…
