Baettig, Pio Spaldin, Nicola A. 2005 We describe the design of a magnetic ferroelectric with large spontaneous magnetization and polarization using first-principles density functional theory. The usual difficulties associated with the production of robustly insulating ferromagnets are circumvented by incorporating the magnetism through <i>ferri</i>magnetic behavior. We show that the ordered perovskite Bi₂FeCrO₆ will have a polarization of ~80 <i>µ</i>C/cm², a piezoelectric coefficient of 283 <i>µ</i>C/cm², and a magnetization of ~160 emu/cm³ (2 <i>µ</i>_<i>B</i> per formula unit), far exceeding the properties of any known multiferroic. application/pdf https://folia.unifr.ch/global/documents/299933 https://folia.unifr.ch/documents/299933/files/1_baettig_aip.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1063/1.1843290 info:eu-repo/semantics/openAccess License undefined Applied Physics Letters. - 2005, vol. 86, no. 1, p. 012505 info:eu-repo/classification/udc/54 Ab initio prediction of a multiferroic with large polarization and magnetization http://purl.org/coar/resource_type/c_6501
