Abstract
The magnetic properties of KDP crystals were experimentally investigated by measuring the torsional rigidity of a high-quality mechanical oscillating system in a magnetic field. It is shown that real KDP crystals, grown in laboratory and factory conditions, specially purified or containing traces of impurities (not more than 10−3 mole %), exhibit magnetic anisotropy. A relation is found between the anisotropy of the magnetic susceptibility (Δχ) and the magnetic field. The magnetic fields where Δχ becomes constant (H ≥ 400 Oe) were determined. The values of Δχ at these fields for different KDP specimens did not exceed 3·10−8. The method can be used to determine the magnetic anisotropy of any dielectric substance.
