Large soft ferrite toroids & slabs in various Ni-Zn compositions were developed for high frequency switching magnets (kickers) & fast rise time current monitors of 450 MeV Electron Accelerator. The electric & magnetic properties of large ferrite ring cores were obtained using a special sintering process. These magnetic properties include a high saturation flux density, high initial permeability, low coercivity, large µQf products (at ^B:100mT, f = 20 MHz) & low loss rf characteristics at high magnetic amplitudes.
