Giant nonlinear transport response in a magnetic semiconductor induced by electrostatic gating
Original language description
Nonreciprocal and nonlinear transport responses enable key functionalities for energy harvesting, frequency mixing, and magnetic-state detection. Traditionally, nonlinear conduction has been observed in non-centrosymmetric crystals or in ferromagnet/heavy-metal heterostructures. Here, we demonstrate a new mechanism for generating strong nonlinear transport in chromium sulfide bromide (CrSBr), a magnetic semiconductor with a centrosymmetric crystal structure. Instead of relying on a crystal lattice or heterostructure to break the requisite symmetries that prohibit nonlinear transport, we directly utilize gate voltage to induce an asymmetric band structure in the magnetic semiconductor through Rashba spin-orbit coupling (SOC), resulting in intrinsic transport nonreciprocity and nonlinearity. Remarkably, the strength of the observed nonlinearity exceeds typical magnetic heterostructure values by several orders of magnitude. Furthermore, the nonlinear transport demonstrates a high tunability with the applied gate voltage, explained by a minimalistic two-band model. These findings establish magnetic semiconductors as powerful platforms for exploring the interplay between SOC and magnetism and for advancing our understanding of nonreciprocal electronic transport. © 2025 The Author(s)
