Multiferroicity in rare-earth nickelates RNiO3.
We show that charge ordered rare-earth nickelates of the type RNiO3 (R = Ho, Lu, Pr and Nd) are multiferroic with very large magnetically-induced ferroelectric (FE) polarizations. This we determine from first principles electronic structure calculations. The emerging FE polarization is directly tied to the long-standing puzzle of which kind of magnetic ordering is present in this class of mater...

متن کاملRare Earth Elements Profile
Definitions and characteristics The rare earth elements (REE) (sometimes referred to as the rare earth metals) are a group of 17 chemically similar metallic elements, including the 15 lanthanides, scandium and yttrium. The lanthanides are elements spanning atomic numbers 57 (lanthanum, La) to 71 (lutetium, Lu) (Table 1). The lanthanides all occur in nature, although promethium, the rarest, only...
متن کاملRare-Earth Separation Using Bacteria
The rare-earth elements are critical to many green energy technologies but are difficult to separate from one another because of their chemical similarity. We demonstrate an alternative, biogenic method based on the adsorption of lanthanide to the bacterium Roseobacter sp. AzwK-3b, immobilized on an assay filter, followed by subsequent desorption as a function of pH. The elution desorption data...
متن کاملRare earth spectrocopy for biophotonics
Luminescence is now extensively used in biology since it constitutes as a very sensitive way of investigations. Several applications of fluorescence concern immunoassays, DNA hybridization, protein interactions, cell imaging, Lab-on-chip etc.;; As non biological fluorescent probes, organic dye molecules and semiconductors quantum dots are the most popular. However, they suffer from drawbacks wh...
