Spin Rotation in -Fe2O3 Nanoparticles by Interparticle Interactions

Interparticle interactions between water molecules

*Correspondence: Makoto Yasutomi, Department of Physics and Earth Sciences, Faculty of Science, University of the Ryukyus, Senbara 1, Nishihara-Cho, Okinawa 903-0213, Japan e-mail: [email protected] We determined many functional representations of interparticle interactions between water molecules, all of which reproduce the experimentally measured density-temperature relation at 1 bar...

Emergent interparticle interactions in thermal amorphous solids.

Amorphous media at finite temperatures, be them liquids, colloids, or glasses, are made of interacting particles that move chaotically due to thermal energy, continuously colliding and scattering off each other. When the average configuration in these systems relaxes only at long times, one can introduce effective interactions that keep the mean positions in mechanical equilibrium. We introduce...

Interparticle Interactions in Annealed FePt Nanoparticle Assemblies

Thermal treatment of self-assembled FePt nanoparticles reduces the interparticle distances, resulting in dramatic changes in the type and strength of interparticle interactions. Consequently, magnetic properties such as the hysteresis and magnetization reversal mechanisms are strongly affected. It is suggested that controlled annealing of self-assembled nanoparticles may offer a novel approach ...

Chemical distinction by nuclear spin optical rotation.

Nuclear spin optical rotation (NSOR) arising from the Faraday effect constitutes a novel, advantageous method for detection of nuclear magnetic resonance, provided that a distinction is seen between different chemical surroundings of magnetic nuclei. Efficient first-principles calculations for isolated water, ethanol, nitromethane, and urea molecules at standard laser wavelengths reveal a range...
