Spintronics Laboratory · Academia Sinica
We study topological materials, spin dynamics, and microscopic magnetic structures at the intersection of fundamental physics, precision experiments, and future information technologies.
Research Focus
We combine material growth, magnetic measurements, and simulation to understand how spin is generated, transported, and coupled to microscopic structures.
Explore magnetic order, phase transitions, exciton–spin interactions, and interfacial ferroelectricity in atomically thin materials.
Study magnetic proximity effects, interfacial anisotropy, and charge–spin coupling in magnetic-film and topological-material heterostructures.
Investigate anomalous Hall effects, Berry curvature, band filling, and thermoelectric transport in topological materials.
Study spin currents, spin pumping, spin-wave propagation, and interactions between spin waves and domain walls.
Experimental Capabilities
We combine thin-film preparation, structural characterization, and physical-property measurements to investigate magnetic materials, thin-film heterostructures, and their electrical transport behavior.
Purpose
Uses plasma sputtering to deposit metal, alloy, and oxide films for nanoscale films and multilayer structures.
Principle
Ions in a plasma strike a target and eject atoms that deposit on a substrate as a thin film; rapidly rotating turbomolecular-pump blades transfer momentum to gas molecules to maintain high vacuum.
Purpose
Deposits thin films in high vacuum for magnetic, superconducting, and related heterostructures used in interface and thin-film studies.
Principle
Ions in a plasma strike a target and eject atoms that deposit on a substrate as a thin film; the cryopump captures gas molecules on cold surfaces to maintain high vacuum.
Purpose
Characterizes crystal structures, phase composition, and the crystallinity of thin-film materials.
Principle
A periodic crystal lattice produces Bragg diffraction of X-rays, and the angles and intensities of the diffraction peaks reveal crystal structures and phase composition.
Purpose
Characterizes spin waves and magnetization dynamics in materials.
Principle
Laser photons scatter inelastically from magnons in the material, and the frequency shift of the scattered light is used to analyze spin waves.
Purpose
Provides controlled temperature and applied magnetic field environments for electrical-transport measurements of thin films and quantum materials.
Principle
The voltage and current response of a sample is measured under controlled temperature and magnetic field to obtain resistance and other electrical-transport properties.
Purpose
Measures magnetization with high sensitivity to reveal how material magnetism varies with temperature and applied magnetic field.
Principle
Quantum interference produced by Josephson junctions and magnetic-flux quantization converts extremely small changes in magnetic flux into a measurable signal.

We welcome people interested in spintronics, low-dimensional magnetism, and quantum materials. Whether you are beginning with a research project or pursuing advanced degree and professional research, we invite you to get in touch.
We explore ferromagnetism, antiferromagnetism, and multiferroicity in atomically thin materials, including magnetic order, phase transitions, exciton–spin interactions, and magnetoelectric coupling.
We study how spin currents are generated, transported, detected, and controlled through spin Hall effects, spin–orbit torque, spin pumping, spin Seebeck effects, spin waves, and domain-wall dynamics.
We prepare magnetic thin films and heterostructures to investigate magnetic proximity effects, interfacial anisotropy, Dzyaloshinskii–Moriya interaction, and charge–spin coupling.
We investigate anomalous and topological Hall effects, Berry curvature, Weyl semimetals, and topological spin structures in magnetic and topological materials.
Members can participate across the research workflow, from thin-film preparation and structural characterization to low-temperature magnetic and electrical measurements using facilities such as XRD, PPMS, and SQUID, alongside data analysis, simulation, and international collaboration.
