The exchange-spring magnet: a new material principle for permanent magnets
E. Kneller,R. Hawig +1 more
TL;DR: In this article, permanent magnets can be made of composite materials consisting of two suitably dispersed ferromagnetic and mutually exchange-coupled phases, one of which is hard magnetic in order to provide a high coercive field, while the other may be soft magnetic, just providing a high saturation J/sub s/, and should envelop the hard phase regions to prevent their corrosion.
Journal ArticleDOI
Relation between anhysteretic and static magnetic tape parameters
E. Kneller,E. Koster +1 more
TL;DR: In this paper, the anhysteretic initial susceptibility of recording tape like materials is calculated from a dynamic mean field model and is given as an explicit function of the static magnetic tape parameters M s (spontaneous magnetization of the magnetic material), p (volume fraction of the magnet material), m R (remanence to saturation ratio of the tape), and H R (residual coercivity of tape) for the case of particles with predominant shape anisotropy.
Journal ArticleDOI
Static and anhysteretic magnetic properties of tapes
TL;DR: In this article, the anhysteretic remanence of solidified suspensions of magnetic particles with predominant shape anisotropy is calculated from first principles for small dc fields H o and arbitrary temperature T (blocking temperature), describing the particle interactions by a mean field and assuming constant decrement of the ac field.
