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…
Scaling of nonlinear susceptibilities in artificial permalloy honeycomb lattice
A. Dahal, Y. Chen, B. Summers +1
Two-dimensional artificial magnetic honeycomb lattice is predicted to manifest thermodynamic phase transition to the spin solid order ground state at low temperature. Nonlinear sus…
