Magnetic semiconductor quantum dots with a few carriers represent an interesting model system where ferromagnetic interactions can be tuned by voltage. By designing the geometry of a doped quantum dot, one can tailor the anisotropic quantum states of magnetic polarons. The strong anisotropy of magnetic polaron states in disklike quantum dots with holes comes from the spin splitting in the valen...
Recent experiments [Jo, Science 325, 1521 (2009)] have presented evidence of ferromagnetic correlations in a two-component ultracold Fermi gas with strong repulsive interactions. Motivated by these experiments we consider spin drag, i.e., frictional drag due to scattering of particles with opposite spin, in such systems. We show that when the ferromagnetic state is approached from the normal si...
Double-shell cobalt monoxide (CoO) hollow particles were successfully synthesized by a facile and effective one-pot solution-based synthetic route. The inner architecture and outer structure of the double-shell CoO hollow particles could be readily created through controlling experimental parameters. A possible formation mechanism was proposed based on the experimental results. The current synt...
The reverse co-precipitation method was used for synthesis of the pure phase multiferroic BiFeO3 (BFO) nanoparticles. Influence of different pH values on the microstructure and magnetic properties of the BFO nanopowders was investigated. Thermogravimetric-differential thermal analysis (TG-DTA) technique indicated that the optimal temperature for calcination is 550°C. The phase formation and the...
