- 01 Nov 2000
TL;DR: In this paper, the effect of magnetic disorder on the magnetization reversal process in thin Co/CoO-films has been investigated and the existence of a disorder-driven critical point in the non-equilibrium phase diagram has been established.
Low-Temperature Magnetic Properties of Co Antidot Array
TL;DR: In this article, the anomalous temperature dependences of coercivity and squareness are discussed by considering the pinning effect of the antidot and the magnetocrystalline anisotropy.

Measurement and modeling of the anhysteretic magnetization of magnetic cores for temperature and frequency dependent effects
J. Walker
- 01 Jan 2007
TL;DR: In this article, an addition to the present model found in many Spice type environments, Jiles-Atherton, is the subject of this work, which adds such a dependence on temperature first followed by frequency.
Comparison of Limiting Loop Model and Elemental Operator Model for Magnetic Hysteresis of Ferromagnetic Materials
TL;DR: In this article, a comparative study of two different hysteresis models, the limiting loop model and the vectorial elemental operator model, is presented, which is regarded as a mathematical approach based on the traditional Preisach model.

Magnetic properties of artificially designed magnetic stray field landscapes in laterally confined exchange-bias layers
TL;DR: The presented work intends to investigate the near-field response of magnetic stray field landscapes above generic types of charged DWs as occurring in thin films with in-plane anisotropy and preferential formation of Néel type DWs when disturbed by external magnetic fields.
