Abstract

Magnetism and superconductivity emerge in materials from the competition between various interactions: spin, orbit, phonon, topology, crystal fields, crystal structures, magnetic structures, etc. Pressure, thus the contraction of inter-atomic distance, has been a highly effective tool to perturb the balance of the interaction and to explore the new states of matter. Furthermore, recent studies have revealed that a uni- or bi-axial strain, including compression and stretch, induces physical properties unachievable under hydrostatic compression. For example, uniaxial compression enhances the anisotropic electron transfer and affects the alignments of crystal domains. This talk will briefly review the uni-axial stress application studies for magnetic and superconducting materials, aiming to contribute to guiding those who try to study or engineer materials using strains.

About the Speaker

Takahiro Matsuoka, National Institute of Physics, University of the Philippines Diliman

Takahiro Matsuoka earned his Ph.D. in Science from Osaka University in 2008. His dissertation involves elemental lithium's pressure-induced metal-to-semiconductor transition and the crystal structure transformations under high pressures. Using diamond-anvil cells, he studied those phenomena by electrical resistance, optical reflectance, and X-ray diffraction measurements. Dr. Matsuoka joined the National Institute of Physics at the University of the Philippines Diliman as a Professorial Fellow.
Dr. Matsuoka's research focuses on the new electronic states, such as superconductivity, thermoelectricity, magnetoresistivity, and heavy fermion behavior, that emerge in Weyl semimetals, topological materials, and layered compounds. Dr. Matsuoka uses diamond anvil cells to apply high pressures on materials exceeding 10000 bars, changing the interaction between electrons and magnetic moments and studying new physical phenomena and material functions.
