Abstract :
A quantitative 3D MFM image analysis technique for studying the percolation mechanism is described. The percolation avalanche point measured by this technique is found to be in good agreement with spinstand results such as the onset of supralinear media noise and the third harmonic technique. Local magnetic domain irregularities are observed at the percolation limit
