| Outline of Final Research Achievements |
For conventional spintronic elements, ferromagnetic materials have been mainly used. However, with using antiferromagnetic materials, elements with less power consumption can be fabricated owing to smaller effects of stray field. In this study, we aim at controlling magnetic domains and conducting layers at the domain boundary of pyrochlore iridates, where a spin configuration called all-in-all-out is realized. As a result, we succeeded in independently controlling the magnetic domains of each layer of a pyrochlore iridate heterostructure. In addition, we find conducting layer at the artificial magnetic domain walls. In this study, we demonstrate successful control of antiferromagnetic domains.
