Abstract Temporal changes of the initial susceptibility of ferromagnetic crystals can be measured advantageously via the resonance frequency of an LC-oscillator. Due to its decreasing susceptibility during the magnetic desaccomodation, the crystal under investigation — which is taken as the core of the oscillatory circuit — induces definite changes of the resonance frequency. The essential advantage of this measuring method consists of the digital acquisition of the measured data, which may form the basis of a complete automation of the desaccomodation experiment. This work describes a device, in which all possibilities of automation — offered by this new measuring method — are realized in a consequent manner.
