Abstract: Abstract: Neutron-diffraction and magnetic measurements have been used in order to study the structure and magnetic changes of La0.7Sr0.3Mn1− x Ti x O3 (x=0, 0.10, 0.20, and 0.30) perovskites. Magnetic measurements show that our samples exhibit a ferromagnetic–paramagnetic transition with decreasing temperature. Effects of Ti doping on the magnetic and nuclear structures are studied here by neutron-powder-diffraction for La0.7Sr0.3Mn1− x Ti x O3 (x=0.10, 0.20, and 0.30). Our analysis indicates that the three representative samples, with x=0.10, 0.20, and 0.30, have a hexagonal system of R3¯c space group, and that the magnetic moments order ferromagnetically into the (101) crystallographic planes, i.e. the magnetic moments of the Mn ion are in the ac plane, with no component along the b-axis. There is no crystalline structure changes when the Ti doping level increases. [Copyright &y& Elsevier]
