Anomalous vortex dynamics in spin-triplet superconductor UTe
Y. Tokiwa, H. Sakai. S. Kambe, P. Opletal +7
The vortex dynamics in the spin-triplet superconductor, UTe, are studied by measuring the DC electrical resistivity with currents along the -axis under magnetic fields along…
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…
Field-Induced Superconductivity near the Superconducting Critical Pressure in UTe2
Dai Aoki, Motoi Kimata, Yoshiki J. Sato +12
We report the magnetoresistance in the novel spin-triplet superconductor UTe2 under pressure close to the critical pressure Pc, where the superconducting phase terminates, for fiel…
Presence of x-ray magnetic circular dichroism effect for zero-magnetization state in antiferromagnetism
N. Sasabe, M. Kimata, T. Nakamura
X-ray magnetic circular dichroism (XMCD) is generally not observed for antiferromagnetic (AFM) states because XMCD signals from the antiparallelly coupled spins cancel each other.…
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…
Anisotropy of the Upper Critical Field in the Heavy-Fermion Superconductor UTe2 under Pressure
Georg Knebel, Motoi Kimata, Michal Vališka +12
We studied the anisotropy of the superconducting upper critical field in the heavy-fermion superconductor UTe under hydrostatic pressure by magnetoresistivity meas…
