Author(s): Hirofumi Akamatsu, Yu Kumagai, Fumiyasu Oba, Koji Fujita, Hideo Murakami, Katsuhisa Tanaka, and Isao Tanaka A superexchange mechanism between Eu 2+ 4 f spins via the 3 d states of nonmagnetic Ti 4+ ions is proposed through first-principles calculations based on a hybrid Hartree-Fock density functional approach to explain G -type antiferromagnetism in EuTiO 3 . This mechanism is supported by systematic calculatio... [Phys. Rev. B 83, 214421] Published Wed Jun 15, 2011
