文摘

{Y, Gd–Tm}3Co7Al2 compounds crystallize in the CeNi3-type structure. {Gd-Er}3Co7Al2 show ferrimagnetic ordering at 309 K, 209 K, 166 K, 124 K and 84 K. Dy3Co7.68Si1.32 exhibits magnetic transitions at 226 K, 155 K and 42 K. {Tb-Er}3Co7Al2, {Tb, Dy}3Ni8Si and Dy3Co7.68Si1.32 are LT soft permanent magnets.
