About awarded research

Title: Nonreciprocal transport properties of GdTiO₃/EuTiO₃ heterostructures grown by gas-source MBE

Abstract : In this study, we fabricated perovskite oxide heterostructures composed of GdTiO₃ and EuTiO₃. Both of Gd³⁺ and Eu²⁺ at A site have 7μ_B magnetic moment, while Ti at B site shows a different valence state (Ti³⁺/Ti⁴⁺), which leads to the magnetic-polar interface system in GdTiO₃/EuTiO₃ heterostructures. In the electrical transport measurement, we successfully observed a rectifying characteristic as nonreciprocal transport properties originating from the magnetism and Rashba spin-split band at the interface of GdTiO₃/EuTiO₃ heterostructure. These new findings suggest that this artificial heterostructure is an ideal magnetic Rashba system to investigate novel transport phenomena.

Your impression & future plan

I am very honored to be recognized as one of the Best Presentation Awards. I would like to express my deepest gratitude to Prof. Masashi Kawasaki and all the collaborators for their kind support along my research.
