Outline of Final Research Achievements

Pyrochlore oxides possessing all-in-all-out spin ordering have attracted burgeoning interest as a new topological candidate material called Weyl semimetal. In this research, we have tailored pyrochlore iridate single-crystaline films and heterostructures, and then investigated a nontrivial metallic surface state appearing at all-in-all-out/all-out-all-in single magnetic domain wall formed at the heterointerface.
