资源简介：
Four 52-metal-ion 3d–4f cluster complexes featuring
a common
core of Ln42M10 (Ln = Gd3+, Dy3+; M = Co2+/3+, Ni2+) were obtained
through self-assembly of the metal ions templated by mixed anions
(ClO4– and CO32–). Magnetic studies revealed that the Gd42Co10 and Gd42Ni10 clusters exhibit the largest
magnetocaloric effect (MCE) among any known 3d–4f complexes.
Replacement of Gd3+ ions with anisotropic Dy3+ ions caused significant changes in the magnetic behavior of the
clusters; both Dy42Co10 and Dy42Ni10 displayed slow relaxation of the magnetization.
