 Title    209Bi N Q R Powder Spectra Influenced by Local and Applied Magnetic Fields  
 Abstract    Several experimental techniques have shown evidence for the existence of internal magnetic fields of the order of 200 G in oc-Bi20 3 [1]. The asymmetrical 209Bi N Q R lineshapes in Bi30 4Br also point to a source of poorly resolved splitting present in this compound. In order to obtain further insight into the origin of the local magnetic fields in these compounds the 209Bi N Q R lineshapes of polycrystalline a-Bi20 3 and Bi30 4Br were recorded in weak (below 500 G) static magnetic fields. A calculation of the expected powder lineshapes in a-Bi20 3 under the influence of the internal and applied magnetic fields up to 1 kG was made. The results of the computer simulation are compared with the lineshapes recorded. From the 209Bi lineshapes ob­ served in the experiment, the local magnetic field at one of the two Bi-sites in Bi30 4Br was estimated.
