Magnetic and electrical resistivity of RT2X2, RTX2 and RTX intermetallic compounds

Ac susceptibility and electrical resistivity studies were carried out on some RT2X2, RTX2 and RTX intermetallic compounds. The Néel temperatures of these compounds are between 3 K for TmCo2Si2 up to 75 K for TbRh2Ge2. The temperature dependencies of the electrical resistivity at high temperatures are typical of metallic conductivity. Anomalies in the temperature dependence of the resistivity near the Néel temperature are observed.
