## Abstract The B1 (NaCl) and B2 (CsCl) structure of rare‐earth monochalcogenides XY (X = La, Ce, Eu, and Y = S, Se, and Te) were investigated with the full‐potential linearized‐augmented plane wave (FP‐LAPW) scheme in the frame of the generalized gradient approximation (GGA). The optimized lattice
