Vibrating sample magnetometer to study the static magnetic properties of various solid samples in magnetic fields up to ±25 kOe is described. The source of the magnetic field is an electromagnet designed by I. M. Puzey. The temperature of the investigated sample varies from 77–370 K by flow cryostat. Magnetic measurements were performed by the direct method. Mechanical vibrations of the sample are created by a vibrator of the original design. The relative instability of the oscillation amplitude is 10–4, and frequency – 10–5. Registration of useful signal is carried out by the system consisting of four pickup coils. The vibrating sample magnetometer allows to receive the magnetic-field, temperature and angular dependencies of the magnetic moment. The dynamic range of the device is 5•10 –6–100 emu.
