In this work, we have discovered the anisotropic near-zero thermal expansion (NZTE) behavior in a family of compounds REAg Ga ( RE = La-Nd, Sm, Eu, and Yb). The compounds adopt the CeAlGa structure type and were obtained as single crystals in high yield by metal flux growth technique using gallium as active flux. Temperature-dependent single crystal X-ray diffraction suggests that all the compounds exhibit near zero thermal expansion along c direction in the temperature range of 100-450 K.
