摘要: The magnetic properties and magnetocaloric effect (MCE) in EuTi1-xCoxO3 (x=0, 0.025, 0.05, 0.075, 0.1) compounds have been investigated. When the Ti4+ ions were substituted by Co2+ ions, the delicate balance was changed between antiferromagnetic (AFM) and ferromagnetic (FM) phases in the EuTiO3 compound. In EuTi1-xCoxO3 system, a giant reversible MCE and large refrigerant capacity (RC) were observed without hysteresis. The values of-△ SMmax were evaluated to be around 10 J·kg-1·K-1 for EuTi0.95Co0.05O3 under a magnetic field change of 10 kOe. The giant reversible MCE and large RC suggests that EuTi1-xCoxO3 series could be considered as good candidate materials for low-temperature and low-field magnetic refrigerant.
