First-order magnetic transition inYb2Ti2O7

Investigations of the first order magnetic phase transition in dysprosium

The first order magnetic phase transition in polycrystalline sample of dysprosium (Dy) has been investigated in detail by dcresistance vs. temperature (R-T) measurements. Distinct signature of coexistence of two magnetically ordered phases (i.e. ferromagnetic and antiferromagnetic), originating as a result of the metastable behavior associated with the first order phase transition (FOPT) is fou...

Imaging the first-order magnetic transition in La0.35Pr0.275Ca0.375MnO3.

The nature of the ferromagnetic, charge, orbital, and antiferromagnetic order in La0.35Pr0.275Ca0.375MnO3 on the nano- and microscale was investigated by photoemission electron microscopy (PEEM) and resonant elastic soft x-ray scattering (RSXS). The structure of the ferromagnetic domains around the Curie temperature T(C) indicates that they nucleate under a high degree of lattice strain, which ...

Stripe-tetragonal first-order phase transition in ultrathin magnetic films

We analyze the nature of the phase transition from a smectic stripe phase to a tetragonal phase predicted in analytic studies by Abanov et al. @Phys. Rev. B 51, 1023 ~1995!# and observed in experiments on ultrathin magnetic films by Vaterlaus et al. @Phys. Rev. Lett. 84, 2247 ~2000!#. At variance with existent numerical evidence, we show results of Monte Carlo simulations on a two-dimensional m...

Simple model of first-order phase transition

One-dimensional model of a system where first-order phase transition occurs is examined in the present paper. It is shown that basic properties of the phenomenon, such as a well defined temperature of transition, are caused both by existence of a border between the phases and the fact that only in the vicinity of that border it is possible for molecules to change their phase. Not only the model...
