A Search for New Permanent Magnet Materials: Crystallographic and Magnetic Properties of New Compounds

  • Chapter
Concerted European Action on Magnets (CEAM)

Abstract

Permanent magnet materials are characterized by high Curie temperature, large spontaneous magnetization and large magnetic anisotropy. The best natural elements to produce these properties are rare earth and transition elements (Fe and Co). New materials could be obtained by addition of others elements such as B, Si or C which stabilized the corresponding atomic structures. New compounds have been synthetized and their crystallographic and magnetic properties have been studied : Nd(CoxMn1-8)12, Nd(N1xMn1-x)12, RFe10SiC0.5 (R = Ce, Pr, Nd, Sm), DyFe2SiC, DyFe2Si2C, R(FexCo1-x)10SiC0.5. Curie temperatures of 950 K for NdCo10SiC0.5 and 670 K for SmCo10SiC0.5 were measured.
