Physics of the Earth and Planetary Interiors, 2006 First-order reversal curve (FORC) diagrams were modelled and experimentally measured for different assemblages of single-domain (SD) magnetite particles with bimodal distributions of coercivities, and varying concentrations. When fitting end-member FORC diagrams to the FORC diagrams of mixtures, linear additivity is obeyed for the non-interacting ...

High-frequency GMI hysteresis effect analysis by first-order reversal curve (FORC) method
Journal of Magnetism and Magnetic Materials, 2021Abstract In this work, we investigate the giant magnetoimpedance (GMI) hysteresis at high-frequency (10 MHz – 1 GHz) of Co-based amorphous magnetic ribbons. The first-order reversal curve (FORC) method was used to analyze their hysteretic behavior present at a low magnetic field (below 7 Oe).

Abstract High-resolution first-order reversal curve (FORC) diagrams are increasingly employed to characterize magnetic minerals in sediments, and especially as a magnetofossil detection tool. Conventional processing protocols, however, are not well suited for this purpose because the opposed needs of high resolution and smoothing of noisy data over ...

First‐order reversal curve (FORC) diagrams are a new technique for identifying magnetic minerals and characterizing their domain structures and interactions. FORC diagrams have potentially important applications for determining magnetic mineral compositions and grain sizes in paleomagnetism and environmental magnetism.

First-order reversal curve (FORC) diagrams have been experimentally shown to be a better way of discriminating domain states in a sample compared to the straightforward use of major hysteresis loops. In order to better understand the fundamental behavior of assemblages of single-domain (SD) grains, we used a micromagnetic model witha conjugate gradient

Abstract The effect of interactions on the soft and hard phases and interference region that commonly appears in the First Order Reversal Curve (FORC) of interacting two-phase magnetic systems was investigated. To obtain an interacting two-phase system, a new method was introduced for the first time to electrodeposit a two-phase magnetic nanowire (NW)

First Order Reversal Curves (FORC) Diagrams of Co Nanowire Arrays
Journal of Nanoscience and Nanotechnology, 2008Nanowire arrays of Co and Ni have been obtained by current pulse electrodeposition into nanoporous alumina templates. By adjusting the pH of the bath, the microstructure of the Co wires was tailored, resulting in two types of arrays of crystalline Co—hcp, with c-axis nominally parallel (Co (c∥)), or nominally perpendicular (Co (c⊥)) to the wire.

Micromagnetic and Preisach analysis of the First Order Reversal Curves (FORC) diagram
Journal of Applied Physics, 2003The First Order Reversal Curve (FORC) diagrams of interacting single-domain ferromagnetic particle systems have been found experimentally to contain negative regions. In this paper, we use micromagnetic and phenomenological (Preisach-type) models to help explain the occurrence of these negative regions.
