SPIN LAB (Yamashita Laboratory) is a spintronics research group at the Faculty of Information Science and Electrical Engineering, Kyushu University, established in January 2025. Our research covers three areas: ferrimagnetic garnets, semiconductor spintronics, and spin caloritronics.
2026-09-01 【Publication】Our paper "Observation of Double Anomalous Hall Polarity Reversals with Temperature in an Ultrathin Ferrimagnetic Insulator"
— international collaboration with Prof. Saroj Dash's group at Chalmers University of Technology — has been published in APL Materials! >>link

SPIN LAB is newly launched research group at Kyushu University, established in January 2025 and led by Associate Professor Naoto Yamashita. Rooted in fundamental physics and driven by the goal of creating innovative devices, our research focuses on the field of spintronics from three key perspectives: crystal growth, interfacial physics, and device physics. The core of SPIN LAB's research lies in spin currents—the flow of spin angular momentum. We are particularly passionate about understanding and advancing their generation, transport, and control, as these processes: the foundation of innovative spintronic technologies.
Currently, we are working in the following three specific areas in spintronics:
In the largest scale,
we have developed
uniform deposition technology
for electrically switchable
ferrimagnetic garnet.

Thin Solid Films 788, 140176 (2024).
For the first time,
we succeeded in formation of an ohmic contact by a ferrimagnetic metal on non-degenerate n-type silicon.

Physical Review Materials 6, 104405 (2022).
For the first time,
we have generated
spin current in semiconductors
via the spin-dependent Seebeck effect.
