Substitution effects of barium and calcium on magnetic properties of AxSr1-x(Fe0.5Ru0.5)O3 double perovskites (x=0.05, A=Ba,Ca)

Original language description

AxSr1-x(Fe0.5Ru0.5)O3 double perovskites (x=0.05 and A=Ba,Ca) were prepared by a sol-gel method and an effect of the cation substitution at the A site of the crystal structure of SrFe0.5Ru0.5O3 on their magnetic properties was monitored by x-ray diffraction (XRD), magnetic measurements, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and temperature-dependent and in-field 57Fe Mössbauer spectroscopy. Both Ca- and Ba-substituted samples reveal the orthorhombic structure similar to the undoped perovskite; however, the cell volume changes with the substituting ion radius. TEM and SEM micrographs manifest agglomerated nanocrystalline samples with particle sizes of about 20-60, 15-50, and 40-70 nm for the undoped, Ba-doped, and Ca-doped perovskites, respectively. Generally, the magnetic regime of both substituted and undoped perovskites can be described by a spin-glass behavior caused by a spin frustration.
