Tunneling spectroscopic signatures of charge doping and associated Mott transition in -RuCl in proximity to graphite
Xiaohu Zheng, Ke Jia, Junhai Ren +5
The layered Mott insulator -RuCl has been extensively studied as a potential Kitaev quantum spin liquid candidate. Here, by constructing heterostructures with graphite, we…
Magnetic-field-induced Anderson localization in orbital selective antiferromagnet BaMnBi
Takuma Ogasawara, Kim-Khuong Huynh, Stephane Yu Matsushita +6
We report a metal-insulator transition (MIT) in the half-filled multiorbital antiferromagnet (AF) BaMnBi that is tunable by a magnetic field perpendicular to the AF sublatt…
Large negative magnetoresistance in BaMnBi antiferromagnet
Takuma Ogasawara, Kim-Khuong Huynh, Time Tahara +7
A very large negative magnetoresistance (LNMR) is observed in the insulating regime of the antiferromagnet BaMnBi when a magnetic field is applied perpendicular to the dire…
Separate tuning of nematicity and spin fluctuations to unravel the origin of superconductivity in FeSe
Seung-Ho Baek, Jong Mok Ok, Jun Sung Kim +8
The interplay of orbital and spin degrees of freedom is the fundamental characteristic in numerous condensed matter phenomena, including high temperature superconductivity, quantum…
Itinerant antiferromagnetic BaMnPn's showing both negative and positive magnetoresistances
Kim-Khuong Huynh, Takuma Ogasawara, Keita Kitahara +7
We report the discovery of a novel giant magnetoresistance (GMR) phenomenon in a family of BaMnPn antiferromagnets (Pn stands for P, As, Sb, and Bi) with a parity-time…
Manifestation of vibronic dynamics in infrared spectra of Mott insulating fullerides
Yuki Matsuda, Naoya Iwahara, Katsumi Tanigaki +1
The fine structure and temperature evolution of infrared spectra have been intensively used to probe the nature of Jahn-Teller dynamics in correlated materials. At the same time, t…
Electron and hole Dirac cone states in-pairs in Ba(FeAs) confirmed by magnetoresistance
Khuong K. Huynh, Yoichi Tanabe, Katsumi Tanigaki
The quantum transport of Dirac cone states in the iron pnictide Ba(FeAs) with a d-\,multiband system is studied by using single crystal samples. The transverse magnetoresistanc…
