✦ Synopsis

We synthesized CeFe 1Àx M x AsO ðM ¼ Mn; Co; 0 6 x 6 0:5Þ by a solid state reaction. The parent compound CeFeAsO undergoes antiferromagnetic order of the Ce 4f electrons at T N ¼ 3:7 K. It is found that the T N decreases with the Mn substitution and becomes below 2 K at x = 0.2, while the Co substitution increases the T N .
