Magnetic susceptibility of lead sulphide
Tóm tắt
Magnetic susceptibility measurements were carried out on lead sulphide in the form of natural galena crystals, and in the form of crushed powder. The experimental molecular diamagnetic susceptibility value was found to be 93·27×10−6 (in e.m.u./gm.mol.) for the single crystal and 81·84×10−6 for the powdered material. Calculations based on a modified Slater-Angus method showed that the type of bonding is mainly covalent with a partial ionic character.
