Abstract :
The motion of a domain wall under the action of an alternating magnetic field was studied during its interaction with a pinning plane. First and second harmonics of the electronic force were measured by a lock-in amplifier, using a computer-controlled system. Good agreement was obtained between theory and experiment. Therefore, results of these experiments were used to determine the characteristics of the pinning place in the sample. The optimal frequency and amplitude of the exciting field have been investigated using this effect and have been used to develop a magnetic sensor
