Magnetism from the Atom to the Bulk in Iron, Cobalt, and …
Molecular beam deflection measurements of small iron, cobalt, and nickel clusters show how magnetism develops as the cluster size is increased from several tens to several hundreds of atoms for temperatures between 80 and 1000 K. Ferromagnetism occurs even for the smallest sizes: for clusters with fewer than about 30 atoms the magneticWeb

11.2.1 Alnico. Alnico magnets were invented in Japan in the early 1930s. The first compositions did not contain cobalt and were called alni. With the discovery that cobalt enhanced magnetic properties, several compositional variations followed between 1935 and 1974, ending with alnico 9. Alnico is a spinodally-decomposed alloy consisting of two ...Web
