    A system for controllable magnetic measurements of hysteresis and Barkhausen noise

  • Original language description

    A specially developed setup for precise measurement of magnetic hysteresis and Barkhausen noise is presented. The setup combines two main features: 1) an accurate local determination of the magnetic field and 2) an improved feedback control of the magnetization process. The magnetic field is measured by two Hall sensors at different distances above the sample. The sample field is determined by a linear extrapolation of these measured profiles of the tangential fields to the sample surface. A digital feedback loop for precise control of the ac magnetization process is proposed. The feedback algorithm combines two methods of magnetizing signal adjustment: linear corrections of the magnetizing voltage amplitude and phase. The presented system is able to adjust the waveform of the magnetic induction or field to the prescribed sinusoidal or triangular shape. This provides stable and physically accurate results, which are independent of a specific experimental configuration.
