Mixed-valence phenomena associated with the highly correlated narrow-band behaviour of the 4f electrons in rare earths are well documented for a variety of rare-earth chalcogenides, borides and intermetallics (Kondo insulators and heavy fermions). The family of rare-earth fullerides with stoichiometry RE2.75C60 (RE=Sm, Yb, Eu) also displays an analogous phenomenology and a remarkable sensitivit...

Simply mixing layered rare-earth hydroxide colloidal solutions and paratungstate solution at pH > 7 led to directional self-assembly of rare-earth hydroxide nanosheets and paradodecatungstates. These hybrids exhibit efficient energy transfer from the OMCT band to rare-earth ions in the hydroxide layers as well as highly enhanced f-f transitions.

Recently, non-rare-earth motors are attracting more and attention due to the booming of electric vehicle (EV) market and, importantly, increasing price rare-earth magnet material. This paper focuses on performance comparison among a commercial interior permanent (IPM) motor two motors, including synchronous reluctance (SynRM) permanent-magnet-assisted (PMaSynRM). The design procedure develop hi...
