摘要:<正> Since the discovery of R_2Fe_(17)N_y by Coey and Sun

Hong, the intrinsic and extrinsic magnetic properties of these

nitrides have been extensively investigated. Having very good

intrinsic magnetic properties with Curie temperature of 749 K and

room temperature anisotropy field of 14 T superior to Nd_2Fe_

(14)B, and room temperature saturation magnetization of 1.5 T,

the Sm_2Fe_(17)N_y nitride is expected to become new permanent

magnet for application. The Sm_2Fe_(17)N_y nitride with intrinsic

coercivity of 3T has been obtained by mechanical alloying. The

Sm_2Fe_(17)N_y, magnets bonded by metal zinc have intrinsic

coercivity μ_(0i)H_c over 0.5 T and magnetic product (BH)_(max)

about 80 kJ·m~(-3)(10
