Topological kink plasmons on magnetic-domain boundaries

HIGHLIGHTS

• who: Dafei Jin from the Nanoscale Science and Engineering Center, University of California, Berkeley, CA, USA have published the paper: Topological kink plasmons on magnetic-domain boundaries, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
• what: The authors achieve an innovative device design that ensures a constant electron_density n0 throughout the main area of 2DEG, but contains a space-varying magnetic_field B(r)=B(r)^ez 31-33 in the 2DEG. Using the same sample and magnet, the authors examine the nonreciprocal properties of the KMPs in Fig 4a, to explicitly demonstrate the underlying unidirectional character . . .
