Microwave generation in ferromagnetic nonlinear pulse forming lines (NPFLs) depends strongly on material properties, particularly the damped gyromagnetic precession of a ferrite’s magnetic moments. Additionally, temperature-dependent material properties, such as saturation magnetization and coercivity, are critical for assuring stable operation due to their influence on the output center frequency. In this study, we measured the […]

Effects of Nb Content on the Microstructure and Magnetic Properties of the Sm₁.₂Zr₀.₂(Fe₀.₈Co₀.₂)₁₁.₅-ₓ Ti₀.₅Nbₓ (x=0 –0.4, at.%) Alloys

ThMn12-type SmFe12-based magnet is suggested to be a promising permanent magnet because of its intrinsic magnetic properties and thermal stability. However, their potential applications are currently limited, as the existence of a soft magnetic α -Fe phase in the alloy deteriorates the hard magnetic properties. Hence, in this work, Nb element was introduced into the […]
