Efectos intergranulares en perovskitas de manganeso nanocristalinas
Boletín de la Sociedad Española de Cerámica y Vidrio, 2000 Intergranular magnetotransport effects are studied on polycrystalline manganites. Reducing grain size through sol-gel technology allows us to show new results on these materials.

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.ABSTRACT The synthesis of single‐phase La0.35Gd0.35Ca0.3(Mn0.5Co0.1Cu0.1Fe0.1Ni0.1Mg0.1)O3 high‐entropy perovskite oxides was investigated using mechanochemical activation followed by thermal treatments. The influence of milling time (1–150 h) and post‐milling annealing temperature on phase formation, compositional homogeneity, and structural evolution

Advanced Physics Research, Volume 5, Issue 7, July 2026.Active reactance in electro‐thermal memristors emerges intrinsically from rapid thermal switching of device resistance, linking current‐controlled and voltage‐controlled negative differential resistance to neuronal spiking dynamics. Opposing temperature coefficients of resistance give rise to active inductive or capacitive responses, enabling tunable ...

Scaling Behavior and Beyond Equilibrium in the Hexagonal Manganites
Physical Review X, 2012 We show that the improper ferroelectric phase transition in the multiferroic hexagonal manganites displays appropriate symmetry-breaking characteristics for testing the Kibble-Zurek mechanism originally proposed to describe early-universe phase ...

Magnetic La0.7M0.3MnO3 (M = Mg, Ca, Sr, and Ba) Catalysts for Next‐Generation MFC Air‐Cathodes
ChemCatChem, Volume 18, Issue 14, 29 July 2026.This study investigated La0.7M0.3MnO3 (M = Mg, Ca, Sr, and Ba) perovskites as new cathode materials for microbial fuel cells (MFCs) by adjusting their magnetic structure. The results show that there is a correlation between intrinsic magnetism and oxygen reduction activity (ORR), which can enhance electron transfer and improve the performance of MFC ...

Crystalline structure and electrical properties of Dy1-XCaXMnO3 solid solution
Boletín de la Sociedad Española de Cerámica y Vidrio, 2002 Solid solutions corresponding to the Dy1-xCaXMnO3 system, x=0.0 to 0.60 have been studied. The powders were prepared by solid state reaction of the corresponding oxides and carbonates. Sintered bodies were obtained by firing between 1250 and 1450ºC.
