Intrinsic negative magnetoresistance from the chiral anomaly of multifold fermions

Nature Communications
The chiral anomaly - a hallmark of chiral spin-1/2 Weyl fermions - is an imbalance between left- and right-moving particles that underpins phenomena such as particle decay and negative longitudinal magnetoresistance in Weyl semimetals. The discovery that

Large Field‐Like Orbital Torque in FeNi/Cr Heterostructures

Advanced Electronic Materials, EarlyView.
Orbital torque enables field‐free magnetization switching in spintronics. FeNi/Cr heterostructures exhibit a large field‐like orbital torque. This torque originates from a tilted orbital current polarization within the Cr layer, producing a significant z‐component.

Enhancement of carrier transport characteristic in the Sb2Se2Te topological insulators by N2 adsorption

Scientific Reports, 2017
The carrier transport characteristics of Sb2Se2Te topological insulators were investigated, after exposure to different levels of nitrogen gas. The magnetoresistance (MR) slope for the Sb2Se2Te crystal increased by approximately 100% at 10 K after 2-days
