“…Over the past few years, the existence of such like spin domains was inferred from experimental data, namely the observation of minor hysteresis loops for thermal and light-induced thermal transitions [24,25], X-ray diffraction data [26], Raman scattering during the thermal transition [27], and neutron Laue scattering on single crystals [28]. Several models derived mainly from the analysis of domains in magnetic systems such as Preisach type models [24] or the First Order Reversal Curves (FORC) method [29][30][31] revealed that in the case of powder samples the domains may be regarded as independent.…”

a b s t r a c tThe thermal and the light-induced spin transition in [Fe(bbtr) 3 ](ClO 4 ) 2 (bbtr = 1,4-di(1,2,3-triazol-1-yl)) as well as the high-spin ? low-spin relaxation following the light-induced population of the high-spin state below the thermal transition temperature are discussed in relation to the accompanying crystallographic phase transition. The experimental data have exclusively been obtained using optical single crystal absorption spectroscopy.

“…Soon after it was proposed, FORC method became an important experimental approach for interaction evaluation in hysteretic systems for a wide class of different materials ranging from magnetic [35][36][37][38][39][40][41][42] and electric [43][44][45] to spin transition systems [46][47][48][49] . In the case of magnetic nanowire arrays, Spinu et al 37 proposed for the first time FORC as an effective method for magnetic interactions characterization with many other reports following [50][51][52][53][54][55][56] .…”

Interactions and magnetization reversal of Ni nanowires arrays have been investigated by the first order reversal curve (FORC) method. Several series of samples with controlled spatial distribution were considered including simple wires of different lengths and diameters (70 nm and 110 nm) and complex wires with single modulated diameter along their length. Subtle features of magnetic interactions are revealed through a quantitative analysis of the local interaction field profile distributions obtained from FORC. In addition the FORC analysis indicates that the nanowire systems with a mean diameter of 70 nm appear to be organized in symmetric clusters indicative of a reversal-field memory effect.

“…examples include the identification of a transition from single domain to a vortex state in nanoscale magnets 27,28 , and one dimensional bubble states which exhibit large coercive fields in Co/Pt multilayers 29 . The FORC method can be extended to any system where the response to an external parameter shows hysteretic behavior 30 . This has been utilized in the study of ferroelectric materials 31 , spin-crossover solids 32 and spin glasses 33 .…”

First-order reversal curve measurements of the metal-insulator transition inVO2: Signatures of persistent metallic domains

et al. 2009

We have performed first order reversal curve measurements of the temperature-driven metalinsulator transition in VO2 thin films, which enable quantitative analysis of the hysteresis behavior. An unexpected tail-like feature in the contour plot of the reversal curve distribution indicates the existence of metallic domains, even at temperatures below the closing of the hysteresis. These domains interact with the surrounding medium and change the reversal path relative to a path from a fully insulating state. With this in mind, and assuming that such interaction persist through the entire phase transition, we develop a model where the driving force (or energy barrier) in charge of opening a hysteresis in VO2 are inter-domain interactions. This model is intrinsically different from the Preisach model usually used to describe hysteresis; given that it looks for the microscopic origin of the hysteresis, and provides physical parameters to characterize it.
