Abstract
We report the finding of unidirectional electronic properties, analogous to a semiconductor diode, in two-dimensional artificial permalloy honeycomb lattice of ultra-small bond, with a typical length of ~ 12 nm. The unidirectional transport behavior, characterized by the asymmetric colossal enhancement in differential conductivity at a modest current application of ~ 10-15 A, persists to T = 300 K in honeycomb lattice of thickness ~ 6 nm. The asymmetric behavior arises without the application of magnetic field. A qualitative analysis of experimental data suggests the role of magnetic charge or monopoles in the unusual observations with strong implication for spintronics.
