Magnetic materials with perpendicular magnetic anisotropy have received much attention due to its advantages in the application of spintronics devices,such as high integration density and low damping
Strontium hexaferrite(SrFe12O19)is of superb qualities such as high Curie temperature(Tc),high saturation magnetization(Ms),high coercivity(Hc),large magnetocrystalline anisotropy(K)and excellent chem
Spin pumping enables the generation of an electric signal in the form of a spin current even in an insulator at room temperature,which encourages efforts to develop a new class of insulator spintronic
Recently,the systems of normal metal(NM)/ferromagnetic metal(FM)have received so much attention,especially the Pt/YIG [Y3Fe5O12] system.The pumping of pure spin current by ferromagnetic resonance and
