Strongly correlated material CeRhIn₅ hosts a helical antiferromagnetic ground state at zero applied field. When a magnetic field of ~30 T is applied slightly away from the c-axis, a new phase emerges within the antiferromagnetic state with an XY electronic nematic character [1]. Here, we use a combination of uniaxial and biaxial strain devices to investigate the nematic susceptibility of CeRhIn₅. A similar approach has been extensively used to investigate the nematic order in iron-based superconductors [2]. We will discuss signatures of the nematic susceptibility in the low-field region of the H-T phase diagram.
