A first order reversal curve investigation of pressure hysteresis in multiferroics spin transition compound

, 2008
International audienceSpin crossover multiferroic [Fe(PM-BiA)2(NCS)2] is investigated for the first time with the first order reversal curve (FORC) diagram method for its hysteretic pressure behavior. The experimental setup allows the measurements of the

Faster modified protocol for first order reversal curve measurements [PDF]

, 2017
In this work we present a faster modified protocol for first order reversal curve (FORC) measurements. The main idea of this procedure is to use the information of the ascending and descending branches constructed through successive sweeps of magnetic ...

Code for 'FORCINN: First-order reversal curve inversion of magnetite using neural networks'

FORCINN is a Python-based package that uses neural network algorithms to invert first-order reversal curves (FORC). The model was trained on a large single-particle magnetite FORC dataset computed by micromagnetic simulations.

Rapid Identification of Greigite in Lacustrine Sediments Using SIRM/χ and χARM: Insights From the Cuo E Core, Tibetan Plateau, China

Earth and Space Science
The Cuo E (CE) core contains the entire Quaternary stratigraphy of the CE Lake (31°24′–31°.32′ N, 91°28′–91°33′E, Tibetan Plateau, China). Here, we study the magnetic properties of 1,748 samples from the CE core, combined with scanning electron ...

Optimization of microstructure for HRE-free Nd-Fe-B magnets with improved properties

Journal of Materials Research and Technology
In this work, we successfully prepared heavy rare earth (HRE)-free Nd-Fe-B sintered magnets with improved coercivity (Hcj) and remanence (Br) by precisely controlling the grain size and optimizing the grain boundaries (GBs).

Modulation of phase boundary and domain structures to engineer strain properties in BNT-based ferroelectrics

Journal of Advanced Ceramics
Bismuth sodium titanate (BNT) ceramics exhibit outstanding strain responses but are unfavorable for application in high-sensitivity displacement actuators due to the large negative strain resulting from irreversible changes in their phase transition and ...
