| Ternary compounds SmNi2Sn2 and SmCu2Sn2 were investigated with the X-ray diffraction, magnetic susceptibility and electric resistivity methods, as well as using the 119Sn Mossbauer effect under the applied magnetic field. Magnetic susceptibilities of these compounds show the Curie-Weiss behaviour in the temperature range from 15 K to 280 K with the enhanced values of the temperature independent term χ0. Both resistivity and magnetic measurements indicate the occurrence of the magnetic ordering in SmCu2Sn2 below TN = 8 K. The Mossbauer investigations carried out at 4.2 K under an applied magnetic field of up 6 T indicate a more complex magnetic structure and a considerable anisotropy. SmNi2Sn2 remains paramagnetic down to 5 K. |
