DOI: 10.1016/j.actamat.2018.02.059
Abstract: Abstract Anomalous divergence of the pearlitic lamellae is typically observed during isothermal eutectoid transformation when the steel composition falls in the three-phase (austenite+ferrite+cementite) region. Here, the transformation progresses such that the composition of austenite changes… read more here.

DOI: 10.1103/physrevb.103.064202
Abstract: Cycloidal spin orders are common in multiferroics. One of the prototypical examples is BiFeO3 (BFO) which shows a large polarization and a cycloidal antiferromagnetic order at room temperature. Here we employ Landau theory and phase-field… read more here.
