The magnetized space material can be later exposed to various shock events (impacts, collisions, Hayabusa type sampling procedure) which have significant demagnetization effect. In order to analyze the coercivity spectra of studied material and evaluate the shock demagnetization level the method based on REM(AF) ratio is applied. The method can be used for identification of the shock history of space materials (chondrules, meteorites, sample returns). Both natural (impacts, collisions) and artificial (Hayabusa type sampling procedure) shock events can be identified.
