摘要: Amorphous latent tracks can be produced in the magnetic insulators, like yttrium iron garnet (Y3Fe5O12 or YIG), by irradiations with swift heavy ions electronic slowing down regime. For this, stopping power must higher than a threshold, around 4.0 keV nm−1 case of YIG, to obtain amorphization material, when irradiation proceeds 0.8–6 MeV amu−1 range. In same energy range, we find that nanophase formed YIG track overlapping. This occurs at fluences depending on power, and corresponding random impacts amorphous tracks. Yet, no subsequent is observed even high fluences. These results are interpreted model based thermal spike induced density ionizations excitations material.
