Thermomagnetic properties, hysteresis properties, NRM stabilities and the study of fine magnetic structures by north seeking bacteria (NSB) were examined. The sample consists of polycrystalline kamacite, taenite and cloudy taenite, while tetrataenite is absent. The NRM directions scattered widely among subsamples, but each subsample was extremely stable against AF demagnetization up to 100mT. The S pole alignments observed by NSB were not parallel completely with the crystallographic axis of kamacite. In order to understand the stable NRM of Nova Petropolis, we must consider the magnetic domains that were reconfigured and stabilized due to deformation by hyper-velocity shocks.}, pages = {189--201}, title = {Characteristics of natural remanent magnetization of Nova Petropolis iron meteorite (II)}, volume = {11}, year = {1998} }
