Giant magnetocapacitance of strained ferroelectric-ferromagnetic hybrids

Coexistence of Phases in Ising Ferromagnets

We derive a new inequality for ferromagnetic Ising spin systems and then use it to obtain information about the number of phases which can coexist in such systems. We show in particular that for even interactions only two phases (up and down magnetization) can coexist below the critical temperature at zero magnetic field (h = 0) whenever the energy is a continuous function of the temperature. W...

Dynamical coexistence of phases in molecular clusters

Two solid structures, a bcc orientationally disordered phase and a strained monoclinic orientationally ordered phase, may coexist for clusters of octahedral molecules. However, this coexistence is more difficult to observe in computer simulations of SF6 clusters than of TeF6 clusters although the SF6 and TeF6 molecules have the same symmetry. This study finds why this difference occurs. On the ...
