Abstract

The temperature dependence of the electrical resistivity of samarium and thulium thin films has been studied in the temperature range from 4.2 K to 300 K. The influence of magnetic structure on the resistivity is clearly seen on the obtained resistivity vs. tem- perature dependences of Sm films prepared by evaporation in high vacuum as well as that of Tm films prepared in UHV. The obtained values of Néel temperatures are lower than those of bulk samples and decrease with decreasing film thickness. Residual resistance ratio exhibits similar behaviour as Néel temperature.
