A hexagonal ordered structure of magnetic columns, which results from an agglomeration of magnetic particles, is obtained in a magnetic fluid film when a magnetic field is applied perpendicularly to the film surface. The evolution of the initially ordered structure in the magnetic fluid film...

We report the first X-ray diffraction and Raman spectroscopy study of a single crystal of the rare-earth endohedral fullerene Dy@C<Subscript>82</Subscript>. The lattice is found to be body-centered cubic (a=25.79 Å, space group <InlineEquation ID="Equ2"> <EquationSource Format="TEX">$I\bar {4}3d)$</EquationSource> </InlineEquation> which is at variance with previous reports and confirms that several...</equationsource></inlineequation></subscript>

We theoretically design and analytically study a controllable beam splitter for the spin wave propagating in a star-shaped (e.g., a Y-shaped beam) spin network. Such a solid state beam splitter can display quantum interference and quantum entanglement by the well-aimed controls of interaction on...
