Did you know?
WebA new aspect of metal oxides -- colossal magnetoresistance exhibited by certain manganese oxides, in particular rare earth manganates of perovskite structure -- has received much attention in the last four years. Some of these oxides show 100% magnetoresistance and have much potential for technological applications. Web2 days ago · By comparatively investigating Dion-Jacobson (DJ) phase 2D perovskites containing different-rigidity organic cations, their stability mechanism is revealed. It is found that a medium-rigidity cation leads to more stabilized connections between organic diammoniums and inorganic octahedra by adjusting their molecular geometries to …
WebAbstract: Bismuth ferrite (BiFeO3) is an attractive multiferroic material that shows strong ferroelectric and antiferromagnetic properties. Nevertheless, producing high-quality oriented BiFeO3 on technology-important platinized silicon substrates by low-cost solution deposition methods is still challenging. WebBismuth ferrite is the most studied one, but rare earth ferrites, manganites and chromites, some double transition metal oxides, mixed manganese oxides and alkaline earth hexaferrites are also being studied in recent years. Some double perovskite compounds …
