The essential modification of the CEF splitting by the Ce impurity appears to be the decisive factor affecting Tc wherein the Ce ion carries zero static magnetic moments similar to the La case. The latter explains the identical dependencies of the ordering temperature on the impurity concentration ...
Fabrication of Zn-bonded Nd–Fe–B magnets by pulsed electric current sintering.Interesting for automotive applications with temperature exceeding 180°C.Variations of pressure and loading factor result in higher density and remanence.Minor diffusion of Zn binder into the MQP-B ribbons is revealed, ...
Further, the skin friction coefficient visualizes a sufficient enhancement for the parameters thermal radiation, surface temperature and magnetic field, but a huge reduction is recorded by promoting the slip factor.doi:10.1016/j.jmmm.2016.08.056A.M. Rashad...
