   Sammanfattning : This thesis focuses on the magnetic properties of a newclass of Nd-based bulk glassyhard magnet, by measuring themagnetization in AC- and DC- fields up to 30 tesla, in thetemperature range 1 - 570 K. The main results of ourinvestigations and analyses in the framework of existing modelsare summarized as follows:1) The bulk glassy Nd-Fe-Al is found to be magneticallyisotropic, with hysteresis losses Wh?120 kJ/m3and maximum energy product (BH)max?2.
