Iron-nickel alloy from iron meteorite Chinga studied by Mossbauer spectroscopy with high velocity resolution

Study of iron-nickel alloy from iron meteorite Chinga using Mossbauer spectroscopy with improved velocity resolution (measurement and presentation in 4,096 channels) revealed sixmagnetic components which may be related to various alpha-Fe(Ni, Co) and gamma-Fe(Ni, Co) phases while previous study with low velocity resolution (in 512 channels) revealed only three magnetic components. This new result was in agreement with the scanning electron microscopy study.
