چکیده انگلیسی
Polycrystalline double perovskite Y2CoMnO6 oxides ceramics sintered at four different temperatures from 1000â¯Â°C to 1300â¯Â°C have been fabricated by conventional sol-gel method. All the Y2CoMnO6 compounds are single phase with monoclinic structure (P21/n space group). The mean grain size grows significantly large and the shape becomes regular obviously with increasing sintering temperature. The effect of sintering temperature on magnetic properties of Y2CoMnO6 compounds has been studied in detail. We found that the oxygen vacancies are introduced by sintering at high temperature has a certain influence on the magnetic properties. Moreover, the magnetic entropy changes (-âSM) as well as relative cooling power (RCP) in the double perovskite Y2CoMnO6 oxides ceramics around paramagnetic to ferromagnetic transition were also investigated.
