Discovery of a high-temperature antiferromagnetic state and transport signatures of exchange interactions in a Bi2Se3/EuSe heterostructure
Ying Wang, Valeria Lauter, Olga Maximova +10
Spatial confinement of electronic topological surface states (TSS) in topological insulators poses a formidable challenge because TSS are protected by time-reversal symmetry. In pr…
Energy gap of topological surface states in proximity to a magnetic insulator
Jiashu Wang, Tianyi Wang, Mykhaylo Ozerov +14
Topological surface-states can acquire an energy gap when time-reversal symmetry is broken by interfacing with a magnetic insulator. This gap has yet to be measured. Such topologic…
Mechanism of magnetic diode in artificial honeycomb lattice
George Yumnam, Jiasen Guo, Yiyao Chen +8
Spin diode is important prerequisite to practical manifestation of spin electronics. Yet, a functioning magnetic diode at room temperature is still illusive. Here, we reveal diode-…
Magnetic charge's relaxation propelled electricity in two-dimensional magnetic honeycomb lattice
Yiyao Chen, George Yumnam, Jiasen Guo +4
Emerging new concepts, such as magnetic charge dynamics in two-dimensional magnetic material, can provide novel mechanism for spin based electrical transport at macroscopic length.…
Quantum disordered state of magnetic charges in nanoengineered honeycomb lattice
George Yumnam, Yiyao Chen, Jiasen Guo +3
A quantum magnetic state due to magnetic charges is never observed, even though they are treated as quantum mechanical variable in theoretical calculations. Here, we demonstrate th…
Local spin ice order induced planar Hall effect in Nd-Sn artificial honeycomb lattice
J. Guo, G. Yumnam, A. Dahal +3
Geometrically frustrated materials, such as spin ice or kagome lattice, are known to exhibit exotic Hall effect phenomena due to spin chirality. We explore Hall effect mechanism in…
