Sažetak
We report ac and dc magnetic susceptibility, dc resistivity, and microstructural investigations of a low U doped YRu2Si2 alloy. Real part of ac susceptibility shows a maximum at around 6.75 K for f = 7 Hz. The temperature of the maximum increases and the magnitude of the maximum decreases with increasing frequency what is a typical spin glass behaviour. Magnitude of the imaginary part depends on frequency too. We show that most of the imaginary part of the susceptibility, for the frequencies we used, comes from conduction electrons. ZFC and FC dc magnetic measurements also indicate the presence of a spin glass transition. Relaxation processes below freezing temperature show ln(t + tO) behaviour. We discuss the origin of the spin glass behaviour in connection with the results of similar investigations found in literature. We note that the microstructural investigations revealed about 7% of the secondary phase in the sample.
