The magnetic and electrical properties of erbium-rich metallic glasses are presented. Magnetic ordering has been observed around 15 K. Below the ordering temperatures a strong local anisotropy develops causing high coercive fields and lack of saturation. The resistivity changes drastically at the ordering temperature and either increases or decreases. The negative temperature coefficients or resistivity at room temperature are explained with the extended Ziman theory. The relationship between the observed kinks in the resistivity curves and the low temperature spin correlations are discussed.
