Stabilization of sample mechanical oscillation parameters in the vibrating magnetometer

Scheme and structure of sample mechanical oscillation parameters stabilization for high temperature vibrating magnetometer in which direct measuring method is used is described. This device allows to reduce significantly error of measuring. The relative instability of vibration amplitude makes 10-4, and frequencies - 10-5. The experimental apparatus is intended for measuring of magnet moment of samples from 5∙10-4 to 50 gs∙cm3 in the range of temperatures 300-1000 K and magnetic fields 0-(±15) kOe.
