Fast control of antiferromagnetic domains via pulsed electric fields in Co3O4 — •Isabel Täuber, Maximilian Winkler, Somnath Ghara, Lilian Prodan, and Istvan Kezsmarki — Universität Augsburg, Deutschland
Co3O4 shows the linear magnetoelectric effect below the Neel-temperature of 30K, with a large magnetoelectric coefficient of 14 ps/m. Besides the typical control of the AFM state by colling with electric and magnetic fields across TN, the domains can be switched by voltage pulses as short as a few ns far below the transition temperature. To improve the application ability, we focus on switching of thin films of Co3O4 single crystals, paving the way for the next generation of spintronics.
Keywords: Co3O4; linear magnetoelectric effect; switching of antiferrromagnetic state
