Abstract: Manipulating of magnetization by electrical current plays a dominating role in recent development of spintronics devices. La0.7Sr0.3MnO3 is a promising perovskite materials exhibits ferromagnetism at room temperature. In this work, magnetic relaxation of La0.7Sr0.3MnO3, which is essential for high speed and low power spintronics, is investigated systematically by angle resolved broadband ferromagnetic resonance. A robust ultra-low damping is observed. Furthermore, we reported anisotropic Gilbert damping and the tuning of such anisotropy through manipulating strain. Possible mechanisms are discussed. In addition, we also investigated the exchange coupling of perovskite heterostructures such as La0.7Sr0.3MnO3 and SrRuO3.
