Size induced magnetic phases in half doped manganite nanowires of La_0.5Sr_0.5MnO₃: a neutron diffraction study

Abstract

field, pressure and biaxial strain. Modification in many physical properties, as well as magnetic properties, is a widely reported phenomenon in nanostructured materials. In complex perovskite oxide one dimensional (1D) nanostructures, studies highlighting structure-magnetic property correlation are not very common. We pursue here crystal and magnetic structure study of half doped manganite nanowires (NWs). Recent reports reveal that the properties of manganites are strikingly altered by nanostructuring [16][17][18][19]-particularly at half doping in nanocrystals (La 0.5 Ca 0.5 MnO 3 ), where size induced destabilization of charge and magnetic ordering was found [4,
