Although no trace of crystahine phases was observed in the electron diffraction pattern, the transmission electron micrograph revealed that there exist clusters, the size of which is about 1 nm, in the present glass. The magnetization measurements showed that this glass is paramagnetic at room temperature. However, the magnetization is high enough for the glass to adhere to a permanent magnet in the Nd-Fe-B system at room temperature.enghttps://creativecommons.org/licenses/by/3.0/de/660Article
