Current-sensitive Hall effect in a chiral-orbital-current state
Yu Zhang, Yifei Ni, Pedro Schlottmann +3
Chiral orbital currents (COC) underpin a novel colossal magnetoresistance (CMR) in ferrimagnetic Mn3Si2Te6 [1]. Here we report the Hall effect in the COC state which exhibits the f…
Transition between heavy-fermion strange metal and quantum spin liquid in a 4d-electron trimer lattice
Hengdi Zhao, Yu Zhang, Pedro Schlottmann +2
We present experimental evidence that a heavy Fermi surface consisting of itinerant, charge-neutral spinons underpins both heavy-fermion-strange-metal (without f electrons) and qua…
Control of chiral orbital currents in a colossal magnetoresistance material
Yu Zhang, Yifei Ni, Hengdi Zhao +5
Colossal magnetoresistance (CMR) is an extraordinary enhancement of the electric conductivity in the presence of a magnetic field. It is conventionally associated with a field-indu…
Transition from Antiferromagnetic to Quadrupole Order in a Modified Square Artificial Spin Ice
Ali Frotanpour, Lance E. DeLong
The results of a numerical study of an ordered substitution of a double-segment into the unit cell of square artificial spin ice are presented. Each pattern vertex has three magnet…
Angular-Dependent Dynamic Response and Magnetization Reversal in Fibonacci-Distorted, Kagome Artificial Spin Ice
Ali Frotanpour, Justin Woods, Barry Farmer +2
We have measured the angular dependence of ferromagnetic resonance (FMR) spectra for Fibonacci-distorted, Kagome artificial spin ice (ASI). The number of strong modes in the FMR sp…
Persistent Insulator: Avoidance of Metallization at Megabar Pressures in Strongly Spin-Orbit-Coupled Sr2IrO4
Chunhua Chen, Yonghui Zhou, Xuliang Chen +12
It is commonly anticipated that an insulating state collapses in favor of an emergent metallic state at high pressures as the unit cell shrinks and the electronic bandwidth broaden…
