摘要:
Sm(C00.87Cu0.13)zalloys were prepared with 7.2⩽z<8. Homogenization heat treatment yielded single‐phase 2:17 material forz≳7.2. Forz=7.8 some of the Co was substituted by Fe. Homogenized alloys remained single phase for up to 15% Co substituted. Remanence valuesBRup to 12.1 kG were reached. Coercive fieldsIHCof 4 kOe were achieved by means of a low‐temperature heat treatment. The magnetization process implies that pinning of the Bloch walls is responsible for the coercivity mechanism.

摘要:
Four different ion acceleration schemes that employ a slow space‐charge wave on an electron beam are suggested and discussed. Also, some of the basic characteristics of such schemes are pointed out.
