Testing the Accuracy of Paleointensity Estimates Using Experimental Pottery Assemblages

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Paleointensity estimates from archaeological pottery represent a key source of information on Holocene variations in geomagnetic field intensity. Yet, pottery rarely exhibits ideal single‐domain behavior that fully satisfies the theoretical assumptions underlying absolute paleointensity methods.

Domain state evolution and magnetic behavior of nickel ferrite nanoparticles: Insights from FORC analysis and structural characterization

open access: yesResults in Physics
In this study, the magnetostructural behavior of nickel ferrite nanoparticles with varying nickel content (x) was systematically examined at annealing temperatures of 250, 500, and 1000 °C.

Exploring the effect of Co concentration on magnetic hyperthermia properties of CoxFe3−xO4 nanoparticles

open access: yesMaterials Research Express, 2020
Although enhanced ferrite nanoparticles (NPs) have been envisioned for use in future biomedical applications, less attempt has been made to tailoring and optimizing their detailed magnetic properties and specific loss power (SLP) values. Herein, Co _x Fe

Electrokinetic analysis reveals common conditioner ingredient interactions with human hair

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 2, Page 379-393, April 2026.
Novel electrokinetic analysis reveals how cationic surfactant deposition on hair is influenced by chain length and counterion mobility. Longer‐chain surfactants show superior adsorption through enhanced van der Waals interactions, while chloride counterions enable stronger electrostatic interactions.

FORC+: A method for separating reversible from irreversible behavior using first order reversal curves

open access: yes, 2016
First Order Reversal Curves (FORCs) have been used for a number of years for the extraction of information from magnetization measurements. The results are most unambiguous for irreversible processes -- for a collection of Preisach hysterons, one gets a "FORC distribution" $ρ(H_{down},H_{up})$, the number of hysterons with given downward \& upward ...

Characterization of the magnetic interactions of multiphase magnetocaloric materials using first-order reversal curve analysis [PDF]

open access: yes, 2015
In order to understand the magnetocaloric response of materials, it is important to analyze the interactions between the different phases present in them.

Subduction Zone Magnetism: The Influence of Metamorphism and Serpentinization in the Mantle Wedge

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Subduction zone magnetic anomalies have previously been used to infer their thermal structure assuming a uniformly serpentinized mantle carries a homogeneous, isotropic magnetization. However, seismic tomography, geological observations and numerical modeling provide increasing evidence for a non‐uniformly serpentinized mantle wedge that may ...

Investigation on non-exchange spring behaviour and exchange spring behaviour: A first order reversal curve analysis

open access: yes, 2013
The First Order Reversal Curve (FORC) method has been utilised to understand the magnetization reversal and the extent of the irreversible magnetization of the soft CoFe2O4-hard SrFe12O19 nanocomposite in the nonexchange spring and the exchange spring ...
