  1. An initio study of magnetoelectric thin films Nicola A.  Spaldin, University of California-Santa Barbara, DMR 0605852 Intellectual Merit: Ferroelectricity induced by thin film heteroepitaxy Magnetic La(Al,Fe,Cr)O3 becomes ferroelectric when constrained to tetragonal symmetry, for example by heteroepitaxial growth on a substrate Origin of Ferroelectricity: under-bonded distortions restore bonding Suppression of tiltings favors polar tetragonal ground state OR non-polar polar A. J. Hatt and N. A. Spaldin, Tri-layer superlattices: A route to magnetoelectric multiferroics? Appl. Phys. Lett. 90, 242916 (2007)

  2. An initio study of magnetoelectric thin films Nicola A.  Spaldin, University of California-Santa Barbara, DMR 0605852 Broader Impact: Student Education UCSB Materials graduate student Alison Hatt traveled to Bangalore, India for a Summer School and research exchange Outcomes: Joint publication with School attendees; on-going collaboration with Bangalore researcher Prof. Shobhana Narasimhan
