[1] We present a highly sensitive and accurate method for quantitative detection and characterization of noninteracting or weakly interacting uniaxial single domain particles (UNISD) in rocks and sediments. The method is based on high-resolution measurements of first-order reversal curves (FORCs). UNISD particles have a unique FORC signature that can be used to isolate their contribution among ...

Ce2Fe14B compound has a great potential to serve as novel permanent magnet alternative thanks the abundant and inexpensive rare-earth element (cerium), while its low magnetocrystalline anisotropy energy product severely restrict applications. In this work, strategy combining melt-spinning electron-beam exposure (EBE) aiming for fabricating high-performance Ce-Fe-B magnetic materials is reported...

We performed a temperature-modulated first-order reversal curve (FORC) study on Pt/Co/Fe/Ir magnetic stack that exhibited phase transition from isolated skyrmions to skyrmion lattice with increasing temperature. Using in situ magneto-optical Kerr imaging, generalized description of domain transformations associated the FORC distribution peaks at both their and sweeping field are derived allow f...

We studied the effect of non-hydrostatic pressure on hysteretic spin crossover in coordination complexes. By introducing into an Ising-like model a double distribution interactions and gap energy, respectively, we were able to generate major hysteresis loop first-order reversal curve (FORC) diagram for spin-crossover systems 106 hysterons (like-spin domains). show that, high gradients around sy...

In this study, two different methods have been used in order to characterize lead-zirconate antiferroelectric thin film elaborated by a modified sol-gel process: First-Order Reversal Curves (FORC) measurements and impedance spectroscopy coupled hyperbolic law analysis. Approaches at low high applied electric fields allow concluding on the presence of weak residual ferroelectric behavior even if...
