Abstract
- The structural and the magnetic properties of spin- and charge-doped Sr0.8La0.2Ti0.9Co0.1O3 have been investigated. The sample shows a cubic structure at room temperature. The temperature dependence of magnetization (M) of Sr0.8La0.2Ti0.9Co0.1O3, in both zero-field-cooled (ZFC) and field-cooled (FC) modes between 100 and 70 000 Oe, was measured. It is found that the sample undergoes the paramagnetic-ferrimagnetic phase transition at around 50 K, and the MZFC curve lies above the MFC one below 32 K when the applied field is less than 2000 Oe. This unusual behavior can be understood as a superposition of ferrimagnetic and paramagnetic contributions to the magnetization. [ABSTRACT FROM AUTHOR]
