AB: Neuschwanstein meteorite (EL-6) fall occurred on April 6, 2002. Total three meteorite bodies were discovered. Our fragments come from a 1750g body found on July 14, 2002. Physical properties of Neuschwanstein meteorite were examined in Solid Earth Geophysics Laboratory, University of Helsinki using standard petrophysical methods. First fragment with fusion crust on one side come from the edge part of the meteorite, while the second fragment consists entirely of interior material. The density (3492 kg/m3, magnetic susceptibility (1), NRM (75 A/m), Q-value (2) and magnetic hysteresis parameters) reflect the EL chondrite range based on meteorite petrophysics database developed by Terho et al. (1996). Magnetic experiments were carried out in order to simulate possible Neuschwanstein magnetizing scenarios and to estimate the magnetizing paleofield. The results indicates that the Neushwanstein is resistant to short time (~ years) viscous terrestrial contamination and the possible extraterrestrial magnetizing fields experienced by the Neuschwanstein meteorite were higher than terrestrial field.
