Popis:	Local magnetic fields Hloc exceeding significantly the magnetic fields produced by nuclear magnetic moments (a few gauss) have been detected in bismuth compounds with valence s and p electrons, which are generally believed to be diamagnetic, by the methods based on measuring the parameters of nuclear quadrupole interactions. Anomalies in the magnetic properties of BiSbO4 and Bi4Si3O12 were clearly manifested when analyzing the line shapes in their 209Bi NQR spectra. The quartet of lines for the lower transition ν1 (Δm = 1/2–3/2) in the spectrum of Bi4Si3O12 in zero external magnetic field and the doublets for the lines of all other transitions in the spectrum of BiSbO4 at unique crystallographic positions of bismuth atoms in the crystal lattices of the compounds suggest a magnetic nature of the splittings. The most probable values of Hloc in these compounds are those in the range from 40 to 100 G.
