Production and Characterization of Nano Crystalline Fe85Si10Ni5 Soft Magnetic Alloys by Mechanical Alloying

Abstract There are various methods to produce iron based nano crystalline magnetic alloys. Among these methods, mechanical alloying is one of the most important. In this research, nano crystalline Fe85Si10Ni5 soft magnetic alloy was synthesized by mechanical alloying. The effect of alloying time on phase constituents and magnetic properties of the produced powders was investigated, by X-ray di...

Sprawl and the Coercive Force of Zoning Law: Fear & Loathing

Although local zoning laws are written to protect the health, safety, and general welfare of community residents, these laws—and the state enabling legislation supporting them—have, in practice, severely limited public participation. Due in part to a general lack of public participation, many local ordinances place homeowners at a distinct disadvantage. For this reason, most citizen groups that...

The coercive force and rotational hysteresis of elongated ferromagnetic particles

2014 The coercive force of an infinite ferromagnetic cylinder is calculated as a function of the radius and of the inclination of the axis to the applied field. For this calculation it is assumed that only curling and rotation in unison take place ; and that whenever the curling is associated with a discontinuous jump, the magnetization is brought to the lower energy state given by Stoner and W...

Phonon dispersions in random alloys: a method based on special quasi-random structure force constants.

In an attempt to obtain reliable first-principles phonon dispersions of random alloys, we have developed a method to calculate the dynamical matrix, with respect to the wavevector space of the ideal lattice, by averaging over the force constants of a special quasi-random structure. Without additional approximations beyond standard density functional theory, the present scheme takes into account...
