Being the first intrinsic antiferromagnetic (AFM) topological insulator (TI), MnBi<sub>2</sub>Te<sub>4</sub> is argued to be a topological axion state in its even-layer form due to the antiparallel magnetization between the top and bottom layers. Here we combine both transport and scanning microwave impedance microscopy (sMIM) to investigate such axion state in atomically thin MnBi<sub>2</sub>Te<sub>4</sub> with even-layer thickness at zero magnetic field. While transport measurements show a zer ...[more]
