We have studied the electrical and magnetic properties on perovskite compounds SrFe(Cr) 0:5Àx Mo 0:5þx O 3 and two-dimensional analogue Sr 2 Fe(Cr) 0:5Àx Mo 0:5þx O 4 . Magnetization measurements have indicated the possibility of ferromagnetism for Sr 2 Fe(Cr) 0:5Àx Mo 0:5þx O 4 as well as threedimensional systems. Electrical resistivity & and ferromagnetic magnetization at 5 K decrease with increasing Mo content x for all titled compounds. Ferromagnetism seems to vanish at around x ¼ 0:4, 0.3 and 0.35 for SrFe 0:5Àx Mo 0:5þx O 3 , SrCr 0:5Àx Mo 0:5þx O 3 and Sr 2 Fe 0:5Àx Mo 0:5þx O 4 systems, respectively. The &'s of SrFe(Cr) 0:5Àx Mo 0:5þx O 3 systems show metallic temperature dependence for x = 0:375, while weak localized feature remains at low temperature for Sr 2 Fe(Cr) 0:5Àx Mo 0:5þx O 4 systems. No significant anomaly such as phase transition has been observed in & down to 0.5 K for SrFe 0:5Àx Mo 0:5þx O 3 with x ¼ 0:4, 0.425 and SrCr 0:5Àx Mo 0:5þx O 3 with x ¼ 0:35.
