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 temperature-dependent hysteresis behavior of both ferrous and multiferroic composites for NPFL applications. We manufactured ferrous materials [nickel zinc ferrite (NZF), yttrium iron garnet (YIG), and cobalt ferrite (CoFe)] using the standard ceramic processing methods and characterized them from 100 to 400 K using vibrating sample magnetometry. Additionally, multiferroic materials were manufactured by adding barium strontium titanate (BST) and were characterized using the same methods.
