The effect of Ni replacement with Ge on the magnetic properties of LaNi5 alloy

In this paper, we present the results of the study on the magnetic properties of LaNi5-xGex (x = 0.1 - 0.5) alloys based on extending the Langevin’s classical theory of paramagnetism. The calculation results show that the number of magnetic particles decreases and the size of magnetic particles increases as the concentration of Ge in LaNi5 alloy increases.
