Abstract
The physical and magnetic properties of permanent magnets compacted from elongated single-domain particles with metal and organic matrices are described. Their unique properties which make possible novel design and application possibilities include: demagnetization curve flexibility; high-energy and energy-to-weight ratio; uniformity of pole face flux; low-temperature coefficient of remanence; precise dimensional tolerances; excellent machinability; solderability; low critical material content; and short radioactive half-life. Compacts have been prepared from iron and iron-cobalt particles with energies of 3.5 million and 5 million gauss-oersteds, respectively. Compacts exposed to 200°C for over one year were observed to change remanence less than 1%.This publication has 4 references indexed in Scilit:
