New possibilities to design artificial magnetic materials for microwave frequencies are considered. Such composites can be used in microwave engineering at frequencies where no natural lowloss magnetic materials are available. A new magnetic particle (metasolenoid) formed by a stack of many parallel and very closely spaced single broken loops is proposed and analyzed analytically, numerically, ...

The analysis of a macroscopical description, in terms of anisotropy constants, of some magnetic transitions in uniaxial systems is presented. The magnetic processes considered are the saturation along a hard direction and the first order magnetization process (FOMP). Evidence is given that a phenomenological description can offer some advantages in the physical interpretation of the mechanisms ...

The rapid thermal processing (RTP) technique features dynamic control of temperature, which permits high heating and cooling rates that cannot be reached with conventional furnace treatments. In recent years, RTP has been increasingly applied to the processing of magnetic materials. The controllable heating profiles provide an approach for the deliberate construction of materials structure via ...
