In-plane electrical impedance as a probe for the electron nematicity of BaFe2As2

In-plane electrical impedance has been examined in as-grown single crystals of BaFe2As2, one of the parent compounds of iron-based superconductors. From the results, it is found that the real part of the impeditivity, namely the AC resistivity, reveals the in-plane anisotropy of the material without...
