چکیده انگلیسی
The crystal and magnetic structures of La0.7Ca0.3Mn0.5Fe0.5O3 compound have been studied by neutron powder diffraction in the temperature range of 10-300 Ð. The magnetization and electrical resistivity measurements have been also performed in the temperature range of 5-300â¯K in magnetic fields up to 1â¯T. These experimental results indicate a formation of a complex magnetic state in which the long-range antiferromagnetic G-type phase coexists with the short-range ferromagnetic clusters. The electrical conductivity of La0.7Ca0.3Mn0.5Fe0.5O3 demonstrates an anomalous temperature behavior suggesting a switching between different states. The origin of the unconventional magnetic state, the mechanisms of the electrical conductivity, and correlation between magnetic and transport properties in this manganite have been discussed.
