Abstract

Rare-earth pyrochlore iridates R2Ir2O7 (e.g., R = Y, rare-earth elements) are an exciting class of quantum materials that exhibit emergent electronic and magnetic phenomena. Ho2Ir2O7 has been identified as a spin-ice on the Ho site due to the strong coupling between localized Ho3+ 4f-electrons and itinerant Ir4+ 5d-electrons. However, the physics was significantly underexplored due to the absence of sizable, high-quality single crystals or films. In this talk, we will present our recent advances in hybrid solid phase epitaxy, which led to the first successful synthesis of high-quality, large-sized (111)-oriented Ho2Ir2O7 thin films.
