Pure SrTiO 3 in bulk form is known to be an 'incipient ferroelectric' where quantum fluctuations of lattice positions prevent long range ferroelectric ordering at finite temperature. We show evidence and identify the origin of ferroelectric relaxation up to nearly room temperature in single crystalline SrT iO 3 . Strikingly, the origin of the observed ferroelectric switching is intrinsic that is coherent switching of surface nanopolar regions and not due to the nucleation and growth of domains, as described by Kolmogorov-Avrami-Ishibashi (KAI) Model.

Highly ordered Bi 2 FeMnO 6 epitaxial thin films have been successfully grown on SrTiO 3 substrate.Both high-flux synchrotron X-ray diffraction reciprocal space mapping and high resolution transmission electron microscopy confirmed the alternative alignment of Fe and Mn along [111] direction of Bi 2 FeMnO 6 films. Magnetic and ferroelectric properties of Bi 2 FeMnO 6 films are characterized and analyzed. The room-temperature ferroelectricity is well kept in Bi 2 FeMnO 6 film as expected.However, it is very interesting that Bi 2 FeMnO 6 film exhibits a typical spin-glass behavior and very weak magnetism rather than a ferri/ferromagnetism as generally believed. Our first-principles calculations suggest a spin frustration model for Bi 2 FeMnO 6 , which can well explain the intriguing magnetic property of Bi 2 FeMnO 6 film.

“…In previous work, 15 room temperature multiferroic properties were reported for Nd: BiFeO 3 / Bi 2 FeMnO 6 bilayer films fabricated by the pulsed laser deposition method, and FM and FE properties were observed. However, due to the appearance of BiFeO 3 , it is hard to subtract the intrinsic magnetic properties of Bi 2 After that, the sample was sintered at 1173 K for 1 h. The sample was characterized by x-ray diffraction ͑XRD͒, XRD Rietveld refinement, scanning electron microscopy ͑SEM͒ equipped with energy dispersive spectroscopy ͑EDS͒.…”

Single phase Bi2FeMnO6 was synthesized on Si substrates by an electrospray method. Three peaks were observed in the temperature dependence of magnetization curve, which is attributed to the inhomogeneous distribution of Fe3+ and Mn3+. The observed magnetic peaks at 150 K, 260 K, and 440 K correspond to orderings of the ferrimagnetic Fe–O–Mn, and antiferromagnetic Mn–O–Mn and Fe–O–Fe, respectively. Heat capacity measurements were carried out to confirm these magnetic transitions. The Debye temperature of Bi2FeMnO6 is 339 K, calculated from Debye–Einstein fitting.
