Abstract. We examine the magnetic properties of four strongly correlated electron compounds based upon the presence or absence of crystallographic disorder and geometric frustration. All four materials (URu₂Si₂, CePd₂Al₃, UNi₄B and URh₂Ge₂) exhibit unusual and not fully understood behavior in their magnetic ordering that are surprising for stoichiometric intermetallic compounds. We summarize these behaviors and relate them to the appearance of disorder and frustration.
