Spectroscopic Evidence for Electron-Boson Coupling in Half-metallic CrO2
Daiki Ootsuki, Hirokazu Fujiwara, Noriyuki Kataoka +9
We report quasiparticle properties of the half-metal ferromagnet CrO2 by means of high-resolution angle-resolved photoemission spectroscopy (ARPES). We clearly observed the Fermi s…

Photoinduced non-reciprocal magnetism
Ryo Hanai, Daiki Ootsuki, Rina Tazai
Out of equilibrium, the action-reaction symmetry of the interactions is often broken, leading to the emergence of various collective phenomena with no equilibrium counterparts. Alt…

Band-selective Plasmonic Polaron in Thermoelectric Semimetal TaPdSe with ultra-high power factor
Daiki Ootsuki, Akitoshi Nakano, Urara Maruoka +6
We report the electronic structure of the thermoelectric semimetal TaPdSe with a large thermoelectric power factor and giant Peltier conductivity by means of angle-resolved…
