Magnetically Driven Spinodal Decomposition as the Origin of Magnetic Softness of CoFeNi‐Based Ferromagnetic High‐Entropy Alloys

ChemPhysChem, Volume 27, Issue 6, 27 March 2026.
Many CoFeNi‐based high‐entropy alloys are soft ferromagnets. Magnetic softness originates from nanostructure formed by spinodal decomposition, where CoFeNi FM nanodomains alternate with nanodomains of other elements. Spinodal decomposition is magnetically driven via the magnetic part of the Gibbs free energy, where the CoFeNi short‐range FM order ...

Step-like features on caloric effects of graphenes

, 2014
We considered a graphene nano-ribbon with a longitudinal electric field (along $x$ direction) and a transversal magnetic field (along $z$ direction), and then observe (i) the electrocaloric effect ruled by an applied magnetic field and (ii) the ...

Sign change of the Grueneisen parameter and magnetocaloric effect near quantum critical points

, 2006
We consider the Grueneisen parameter and the magnetocaloric effect near a pressure and magnetic field controlled quantum critical point, respectively. Generically, the Grueneisen parameter (and the thermal expansion) displays a characteristic sign change
