Micromagnetic Determination of the FORC Response of Paleomagnetically Significant Magnetite Assemblages [PDF]

Geochemistry, Geophysics, Geosystems
Micromagnetic modeling allows the systematic study of the effects of particle size and shape on the first‐order reversal curve (FORC) magnetic hysteresis response for magnetite particles in the single‐domain (SD) and pseudo‐single domain (PSD) particle ...

Magnetic Interactions in Wiegand Wires Evaluated by First-Order Reversal Curves [PDF]

Materials (Basel), 2022
Wiegand wires exhibit a unique fast magnetization reversal feature in the soft layer that is accompanied by a large Barkhausen jump, which is also known as the Wiegand effect.

First-Order Reversal Curves of Sets of Bistable Magnetostrictive Microwires [PDF]

Materials (Basel), 2023
Amorphous microwires have attracted substantial attention in the past decade because of their useful technological applications. Their bistable magnetic response is determined by positive or negative magnetostriction, respectively.

Micromagnetic simulations of first-order reversal curve (FORC) diagrams of framboidal greigite [PDF]

, 2020
Greigite is a sensitive environmental indicator and occurs commonly in nature as magnetostatically interacting framboids. Until now only the magnetic response of isolated non-interacting greigite particles have been modelled micromagnetically. We present

Phase diagrams of forced magnetic reconnection in Taylor’s model [PDF]

Journal of Plasma Physics, 2015
Recent progress in the understanding of how externally driven magnetic reconnection evolves is organized in terms of parameter space diagrams. These diagrams are constructed using four pivotal dimensionless parameters: the Lundquist number $S$, the magnetic Prandtl number $P_{m}$, the amplitude of the boundary perturbation $\hat{{\it\Psi}}_{0}$, and ...

Mesoscale magnetic rings: Complex magnetization reversal uncovered by FORC [PDF]

, 2020
In this work, we investigate mesoscopic amorphous magnetic rings prepared by ion-implantation. The analysis is carried out combining conventional magnetization vs field measurements alongside MOKE microscopy imaging and, for the first time, first-order

First-order reversal curve (FORC) diagrams of nanomagnets with cubic magnetocrystalline anisotropy: a numerical approach [PDF]

, 2018
First-order reversal curve (FORC) diagrams are increasingly used as a material’s magnetic domain state fingerprint. FORC diagrams of noninteracting dispersions of single-domain (SD) particles with uniaxial magnetocrystalline anisotropy (MCA) are well ...

Time‐Asymmetric FORC Diagrams: A New Protocol for Visualizing Thermal Fluctuations and Distinguishing Magnetic Mineral Mixtures

Geochemistry, Geophysics, Geosystems, 2018
First‐order reversal curves (FORCs) are nowadays routinely used to assess domain states and magnetostatic interactions of magnetic minerals. While a huge step forward from bulk magnetic measurements in terms of sample characterization, there is a missing
