Fig. 1: Crystal structure of La2CuO4, Nd2CuO4, and Sr2CuO2Cl2.
From: Thermal Hall conductivity in the cuprate Mott insulators Nd2CuO4 and Sr2CuO2Cl2
Sketch of the crystal structure of the three single-layer cuprate Mott insulators compared in the present study: a La2CuO4, b Nd2CuO4, and c Sr2CuO2Cl2. Note that the small orthorhombic distortion in La2CuO4 below 530 K is not shown here, nor is the tilt in the oxygen octahedra surrounding the Cu atoms.
