About the influence of mechanical comminution processes on saturation magnetization of strontium ferrites

摘要: Abstract The influence of the mechanical comminution process on coercive field hardmagnetic ferrites is well known. But, there a strong effect saturation magnetization strontium ferrite as well. Using special type vibration mill decreases to 0.084 T and increases up 0.22 by further enlarging milling time. approaches 0.41 again subsequent annealing. Preliminary investigations aiming at an interpretation are given.
