Abstract
Magnetism of materials may be adjusted by varying the adjacent magnetic ions in materials, such as Ru4+ in SrRuO3. We here report a study of the structure, electro-transport and magnetic properties of poly-crystallized SrRuxO3, which is synthesized by solid-state reaction. Results show that all the synthesized SrRuxO3 samples remain the single phase, and the grain size increases with increasing the Ru content. A semiconducting behavior with x ≤ 1 and a Fermi Liquid behavior with x > 1 are observed and determined. At 10 K, the saturated magnetic moment increases with x from 21.02 to 29.82 (emu/g), while the coercivity decreases from 5100 to 910 (Oe), which are also confirmed by the first principle calculations.
