Experimental analysis of magnetic accommodation properties via the use of complex trajectories

We present the results of an experimental analysis aimed at characterizing possible accommodation phenomena in soft magnetic materials. The amount of magnetization change and the magnetization stabilization process appear to vary with the trajectory chosen to form minor loops close around corresponding regions of the major loop. We illustrate the adopted strategy to define different paths in the B−H plane forming minor loops attached at the major loop and at different order reversal curves. We also show the use of more complex trajectories. Experimental results are performed on a sample of soft magneic ferrite.
