Characterisation of porous PZT ceramics by first-order reversal curves (FORC) diagrams
Journal of the European Ceramic Society, 2006Abstract The method of investigation based on the first-order reversal curves (FORC) is proposed for describing the role of porosity on the switching properties of Nb–PZT ceramics with anisotropic porosity prepared using lamellar graphite as pore-forming agent.

First order reversal curves (FORCs) as indicators of magnetic PM sources 
2022<p>Real-time monitoring of particulate matter (PM) is performed by traditional air quality monitors using size-fractionated light-scattering laser photometers or gravimetric analysis. However, these quick methods do not fully characterise the particulates, in particular, the more toxic metals such as Fe.

First-Order Reversal Curve (FORC) Measurements for Decoding Mixtures of Magnetic Nanowires
2021The progression of nanotechnology has resulted in the exploitation of very complex magnetic nanostructures with anomalous magnetic responses, which cannot be fully understood using hysteresis loop measurements. First-order reversal curve (FORC) measurements are among the most powerful tools for characterization of complex bulk, micro-, and nano-systems

Experimental first order reversal curves (FORC) on Ising and Heisenberg spin glasses
Journal of Magnetism and Magnetic Materials, 2007Abstract The first order reversal curve (FORC) method is employed to analyse the low temperature hysteresis behaviour of two model 3d spin glasses: the Ising system Fe 0.5 Mn 0.5 TiO 3 and the near isotropic Heisenberg like system Ag(11 at% Mn).

MFM and first order reversal curve (FORC) study of switching mechanism in Co25Pd75 films
Journal of Applied Physics, 2019Recent research on CoPd alloys with perpendicular magnetic anisotropy has suggested that they might be useful as the pinning layer in CoFeB/MgO-based perpendicular magnetic tunnel junctions for various spintronic applications such as spin-torque transfer random access memory.

Review of Scientific Instruments, 2016
Alongside the development of artificially created magnetic nanostructures, micro-Hall magnetometry has proven to be a versatile tool to obtain high-resolution hysteresis loop data and access dynamical properties. Here we explore the application of First Order Reversal Curves (FORC)—a technique well-established in the field of paleomagnetism for ...

Abstract Magnetic nanowires electrodeposited into solid templates are of high interest due to their tunable properties which are required for magnetic recording media and spintronic devices. Here, highly ordered arrays of FeCoNi NWs with varied diameters (between 60 and 150 nm) were fabricated into nanopores of hard-anodized aluminum oxide templates ...

In this paper we present an identification algorithm of the Preisach distribution from the FORC diagram. This method does not imply the use of an analytical function for the Preisach distribution which makes it very useful when such an approximation is not available.

MRS Advances, 2017
First-order-reversal-curves (FORCs) are an elegant, nondestructive tool for characterizing the magnetic properties of materials comprising fine (micron- or nano-scale) magnetic particles. FORC measurements and analysis have long been the standard protocol used by geophysicists and earth and planetary scientists investigating the magnetic properties of ...
