Abstract

SmMIn₅ ( M = Co, Rh, Ir ) crystallizes in the tetragonal HoCoGa₅-type structure. This type of crystal structure is noticed as tetragonal variants of the AuCu ₃-structure, in which new superconductors were discovered. PuCoGa₅ and PuRhGa₅ are also the interesting superconductors. On the other hand, it is expected that Sm has a ground state similar to Pu compounds. We have succeeded in growing single crystals of SmMIn₅ by the flux method. SmRhIn₅ and SmIrIn₅ showed the antiferromagnetic ordering and extra transitions below T_N, which is almost same as the results in the previous report. We have succeeded in growing single crystals of SmCoIn₅. It also showed the antiferromagnetic ordering and extra transitions below T_N = 11.9 K. The temperatures of these anomalies are 6, 7.6 and 11.9 K and lowest found in SmMIn₅ compounds.
