Unique Itinerant Ferromagnetism in 4d-electron System Ca2RuO4
Fumihiko Nakamura, Hiroki Ogura, Tatsuhiro Sakami +1
We have studied the magnetic properties of pressure-induced ferromagnet Ca2RuO4 to reveal the uniqueness of the 4d-electron ferromagnetism in the quasi-two-dimensional conductor. T…
High-order Harmonic Generation and its Unconventional Scaling Law in the Mott-insulating
K. Uchida, G. Mattoni, S. Yonezawa +3
Competition and cooperation among orders is at the heart of many-body physics in strongly correlated materials and leads to their rich physical properties. It is crucial to investi…
Emergence of low-energy electronic states in oxygen-controlled Mott insulator CaRuO
Takeo Miyashita, Hideaki Iwasawa, Tomoki Yoshikawa +7
Insulator-to-metal transition in CaRuO has drawn keen attention because of its sensitivity to various stimulation and its potential controllability. Here, we report a d…
Role of local temperature in the current-driven metal-insulator transition of Ca2RuO4
Giordano Mattoni, Shingo Yonezawa, Fumihiko Nakamura +1
It was recently reported that a continuous electric current is a powerful control parameter to trigger changes in the electronic structure and metal-insulator transitions (MITs) in…
Abnormal flip in coherent phonon oscillations of CaRuO
Min-Cheol Lee, Choong H. Kim, Inho Kwak +9
We employ an optical pump-probe technique to study coherent phonon oscillations in CaRuO. We find that oscillation-amplitude of an symmetric phonon mode is strongly s…
Anomalous Thermoelectric Response in an Orbital-Ordered Oxide Near and Far from Equilibrium
Yasuo Nishina, Ryuji Okazaki, Yukio Yasui +2
We report the thermoelectric transport properties in the orbital-ordered Mott insulating phase of CaRuO close to and far from equilibrium. Near equilibrium conditions where…
