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…

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…
