Abstract
The intermetallic compounds RE (2)Cu(2)Mg and RE (2)Pd(2)Mg (RE=La, Ce) were prepared and characterized by magnetic susceptibility and heat-capacity measurements. They crystallize with an ordered U(3)Si(2) type structure (space group P4/mbm) and the cerium compounds contain stable trivalent cerium ions, which undergo antiferromagnetic ordering at similar to 7.5 and similar to 4 K, respectively. In high magnetic fields Ce(2)Cu(2)Mg exhibits spin reorientation with critical field strength of 40 kOe at 5 K. The data are compared to the non-magnetic isotypic compounds La(2) T (2)Mg (T=Cu, Ni, Pd) and to the already reported intermediate valent Ce(2)Ni(2)Mg.
