What is recorded here?
Two independent experiments reported low-temperature second-order electrical responses in even-layer antiferromagnetic MnBi2Te4 whose signs reverse with prepared antiferromagnetic order. Gao and colleagues engineered black-phosphorus interfaces and supported a predominantly nonlinear Hall response through symmetry, conductivity scaling and frequency-mixing controls. Wang and colleagues measured transverse and longitudinal nonlinear responses in four- and six-layer devices, including current-direction-dependent DC resistance. Their models attribute major contributions to energy-weighted quantum-metric geometry.

Scientific scope

No room-temperature, terahertz, lossless-current or device-deployment claim is established.

Quantum-metric-related nonlinear electrical transport in antiferromagnetic MnBi2Te4
Two independent experiments reported low-temperature second-order electrical responses in even-layer antiferromagnetic MnBi2Te4 whose signs reverse with prepared antiferromagnetic order. Gao and colleagues engineered black-phosphorus interfaces and supported a predominantly nonlinear Hall response through symmetry, conductivity scaling and frequency-mixing controls. Wang and colleagues measured transverse and longitudinal nonlinear responses in four- and six-layer devices, including current-direction-dependent DC resistance. Their models attribute major contributions to energy-weighted quantum-metric geometry.
