MAE MEASUREMENTS USING A 4-POINT METHOD

O. Montero – V. Raposo – D. García – J. Íñiguez – C. de Francisco

   A new method for measuring Magnetic After Effect (MAE) in amorphous materials is here presented. MAE was observed as the decrease of the real and imaginary parts of the complex impedance with time after a sudden change in the applied magnetic field. Real and imaginary parts of the impedance of the sample in the form of a magnetic wire were obtained using a four-point technique with a lock-in amplifier.
