Characterizing magnetofossils from first‐order reversal curve (FORC) central ridge signatures [PDF]

Geochemistry, Geophysics, Geosystems, 2014
The central ridge structure of a first‐order reversal curve (FORC) distribution is indicative of uniaxial noninteracting single domain magnetic particles, which provides the opportunity to identify and characterize biogenic magnetic mineral remains ...

First-order reversal curves (FORCs) of nano-engineered 3D Co-Fe structures [PDF]

AIP Advances, 2020
In this paper we present first-order reversal curve (FORC) diagrams of ensembles of three-dimensional Co3Fe nanostructures as 2 × 2 arrays of nano-cubes and nano-trees.

Avoiding the zero-coercivity anomaly in first order reversal curves: FORC+ [PDF]

AIP Advances, 2019
In conventional FORC (First Order Reversal Curve) analysis of a magnetic system, reversible and low-coercivity irreversible materials are treated as being qualitatively different: the FORC distribution shows low-coercivity materials but completely hides ...

Reverse Magnetization Behavior Investigation of Mn-Al-C-(α-Fe) Nanocomposite Alloys with Different α-Fe Content Using First-Order Reversal Curves Analysis [PDF]

Nanomaterials, 2022
The reverse magnetization behavior for bulk composite alloys containing Mn-Al-C and α-Fe nanoparticles (NPs) has been investigated by hysteresis loops, recoil, and first-order reversal curves (FORC) analysis. The effect of adding different percentages of

Single Diameter Modulation Effects on Ni Nanowire Array Magnetization Reversal [PDF]

Nanomaterials, 2021
Geometrically modulated magnetic nanowires are a simple yet efficient strategy to modify the magnetic domain wall propagation since a simple diameter modulation can achieve its pinning during the nanowire magnetization reversal. However, in dense systems

Low-temperature first-order reversal curve (FORC) diagrams for synthetic and natural samples [PDF]

Geochemistry, Geophysics, Geosystems, 2006
First‐order reversal curve (FORC) diagrams were measured on a variety of synthetic and natural (submarine basalts and potsherds) samples, as well as for a mixture, between room temperature and 10 K. Measuring FORC diagrams allowed us to examine the behavior of the coercivity field and interaction field distributions with decreasing temperature ...

First‐order reversal curve (FORC) diagrams of natural and cultured biogenic magnetic particles [PDF]

Journal of Geophysical Research, 2007
First‐order reversal curve (FORC) diagrams are rapidly becoming a standard tool for characterizing magnetic particles because they simultaneously incorporate information regarding magnetostatic interaction and domain states. The simplest interpretation of FORC diagrams of single‐domain (SD) particles is based on the Neel interpretation of Preisach ...

First-Order Reversal Curve (FORC) Analysis of Magnetocaloric Heusler-Type Alloys

IEEE Magnetics Letters, 2016
The thermomagnetic hysteresis loops of a NiMnInCo Heusler-type alloy exhibiting inverse magnetocaloric effect were studied with the help of first-order reversal curves (FORC). These have been measured using two different protocols (either upon heating or cooling the sample) and using different applied magnetic fields.
