Steven Spurgeon has published a research highlight in the Materials Research Society Bulletin‘s August 2013 issue discussing strain control of magnetic ordering in BiFeO3.

From the article: “Researchers in pursuit of higher density memories have set their sights on a new generation of spintronic materials, in which both electron charge and spin are used to convey information. The magnetoelectric multiferroic BiFeO3 (BFO), which exhibits direct coupling between ferroelectric and antiferromagnetic order, is particularly interesting for such an application. However, the complex interplay of strain and magnetic response in this system is only poorly understood. Now, Daniel Sando and colleagues at the Unité Mixte de Physique CNRS / Thales shed light on the fundamental mechanisms governing antiferromagnetism and demonstrate tunable control of this ordering for spintronics devices.. . . .”

Drs. Ghassemi, Taheri, and colleagues’ latest paper, titled “Stoichiometry of LaAlO3 films grown on SrTiO3 by pulsed laser deposition” has been published online in the Journal of Applied Physics.

From the abstract: “We have studied the stoichiometry of epitaxial LaAlO3 thin films on SrTiO3 substrate grown by pulsed laser deposition as a function of laser energy density and oxygen pressure during the film growth. Both x-ray diffraction (θ-2θ scan and reciprocal space mapping) and transmission electron microscopy (geometric phase analysis) revealed a change of lattice constant in the film with the distance from the substrate. . . .”
