    摘要： There is provided a magnet manufacturing method with which a high residual magnetic flux density is obtained without using dysprosium (Dy) and without using a bonding agent. Magnetic powders made of a hard magnetic material formed of a R—Fe—N compound containing a rare earth element as R or formed of a Fe—N compound are used. In a pressurizing step, the magnetic powders are pressurized by molds multiple times to form a primary compact. In a baking step, a secondary compact is formed by heating the primary compact in an oxidizing atmosphere at a temperature lower than a decomposition temperature of the magnetic powders to bond together the outer surfaces of the adjacent magnetic powders with oxide films formed on the outer surfaces of the magnetic powders.

    摘要： The present invention is directed to a family of trimetallic nitride endohedral metalloheterofullerenes having the formula Ax X3-x N@Cn N, (x=0, 1, 2 or 3) (n=number of carbon atoms in the cage, typically between 59 and 199), wherein A and X are metal atoms encased within the cage, C is carbon and N is nitrogen. A and X are preferably selected from rare earth elements or group IIIB elements. A or X metal atoms are scandium, yttrium, lanthanum, gadolinium, lutetium, holmium, erbium, thulium, dysprosium, neodymium, cerium, praseodymium and ytterbium. Representative embodiments include Sc3N@C79N, Y3N@C79N, La3N@C79N, Tb3N@C79N, Ho3N@C79N, LaSc2N@C79N, PrSc2N@C79N, GdSc2N@C79N, La2ScN@C79N, and Gd2ScN@C79N. The present invention is also directed to a method of making the inventive endohedral metalloheterofullerenes having the formula AxX3-xN@CnN. These methods involve use of oxidizing gases (e.g. O2 and NOx) coupled with combustion as a means for making trimetallic nitride clusters encapsulated in heteroatom CnN cages made of both carbon and nitrogen.
