Systematic powder diffraction studies have been carried out to establish the magnetic phase diagram of La 2Ϫ2x Sr 1ϩ2x Mn 2 O 7 (LSMO327) in a wide hole concentration range (0.30 Յ x Յ 0.50), using the HERMES diffractometer. LSMO327 exhibits a planar ferromagnetic structure for 0.32 Յ x Յ 0.38 at lo
The effect of the partial substitution of Mn with Fe in the layered perovskites (x 0.2) La 1.4 Ca 1.6 Mn 2± ±x Fe x O 7 has been studied. The results show that conduction and ferromagnetism have been consistently suppressed by Fe doping. The colossal magnetoresistance is enhanced by Fe doping in som
