摘要：

SrRuO3 and Sr3Ru2O7 are members of Ruddlesden-Popper (R-P) series. SrRuO3 is a ferromagnetic metal whereas Sr3Ru2O7 is a paramagnetic metal. We have synthesized SrRuO3-Sr3Ru2O7 composite systems and have studied the magnetic, Fermi liquid, non-Fermi liquid behavior and electronic structures of these systems. We observed that magnetization decreases and resistivity increases with increase in Sr3Ru2O7 phase, while the Curie temperature did not show any significant change. Moreover, we observed that Fermi-liquid behavior of SrRuO3 is mostly dominant below 38 K in pure SrRuO3. With increase in Sr3Ru2O7 phase the Fermi-liquid region slightly reduced to below 33 K, whereas the non-Fermi liquid region remained unchanged.
