This information gives us a very helpful classification of levels . In the

hexagonal groups there are a great many symmetry operations ; a full account is

given by KOSTER , by JONES and for h . c . p . the best account is by ALTMANN .

Heusler alloys ( Cu , MnAl ) are ordered ferromagnetic alloys with a

**cubic**structure . The point symmetry of the Cu sites is

**cubic**so that there is noquadrupolar effect . In the ferromagnetic region , NMR experiments have been

done on Cu ...
