Hysteresis losses in a dense superparamagnetic nanoparticle assembly

Superparamagnetic nanoparticle-based viscosity test

Fe3O4-LiMo3Se3 nanoparticle clusters as superparamagnetic nanocompasses.

A scaleable chemical approach to functional nanoscale analogues of the magnetic compasses in magnetotactic bacteria is described. LiMo(3)Se(3)-Fe(3)O(4) nanowire-nanoparticle composites were synthesized by a reaction of 3-iodopropionic acid treated LiMo(3)Se(3) nanowire bundles with oleic acid-stabilized Fe(3)O(4) nanoparticles of 2.8, 5.3, and 12.5 nm size in tetrahydrofuran. Transmission elec...

Superparamagnetic Behavior of the Magnetic Hysteresis Loop in the Fe2O3@Pt Core-Shell Nanoparticles

Studies of the magnetization of Fe2O3@Pt nanoparticles at room temperature showed that there is superparamagnetic contribution with high saturation magnetization about 12.35(emu/g), and soft ferromagnetic contribution with narrow coercive field about 58(Oe). In this paper we fitted the hystersis loop of sample with Brillouin function that demonstrating existence of superparamagnetic phase. Tota...

A simulation study on superparamagnetic nanoparticle based multi-tracer tracking

Hysteresis losses in hollow superconducting filaments and in multifilament systems

The magnetization of hollow superconducting filaments in a perpendicular applied field is calculated numerically using a mathematical model. With this model the hysteresis losses over a closed cycle of the applied field, as well as the instantaneous power dissipation in the filament, can be calculated. Theoretical results are compared with data from experiments using wire with hollow Nb3Sn fila...
