The Influence of Ca Substitution on Magnetic and Electric Properties of GdCoO3- δ Cobaltite

Abstract:

Article Preview

The polycrystal samples of Gd1-xCaxCoO3-δ 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 close to the same of the parent GdCoO3 with Co3+ 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.
