Аннотация: The polycrystal samples of Gd(1-x)Ca(x)CoO(3-delta) with different content of Ca were synthesized by three different techniques: solution method, solid state reaction and a sol-gel method. A study of magnetic and electric properties have been made. It is shown that the magnetic properties of this compound are in a high degree closeПоказать полностьюto the same of the parent GdCoO(3) with Co(3+) ions being in a low spin state below the room temperature. The conductivity investigation revealed its increase by alkaline-earth substitution typical in rare-earth cobaltites.
