Phys. Rev. Lett. 101, 117201 (2008) [4 pages]First-Principles Approach to Lattice-Mediated Magnetoelectric EffectsReceived 22 December 2007; published 8 September 2008 We present a first-principles scheme for the computation of the linear magnetoelectric response of magnetic insulators. We focus on the lattice-mediated part of the response, which we argue can be expected to be dominant in materials displaying strong magnetoelectric couplings. We apply our method to Cr2O3 and show that its low-temperature response has a significant lattice character. © 2008 The American Physical Society URL:
