Research Abstract

In this project, we utilized the angular dependence of magnetic torque as a powerful probe of the "electronic nematicity", which is a state with rotational symmetry breaking recently discussed in strongly correlated electron systems. By using highly sensitive micro cantilever technique, we found in-plane anisotropy of magnetic susceptibility in the normal state of iron-based superconductors as well as in the so-called hidden order phase of heavy-fermion compound URu2Si2. The results established the presence of electronic nematic states in these strongly correlated materials.
