Abstract

Magnetic properties of Ho@C ₈₂ and Gd@C ₈₂ were characterized in the temperature range of 1.8-100 K with an applied magnetic field up to 5 T. The isothermal magnetization curves of Gd@C ₈₂ and Ho@C ₈₂ follow the Brillouin function down to 8 and 12 K, respectively. Unlike Gd@C ₈₂ , the fitting to the Curie-Wiess law for Ho@C ₈₂ results in an effective magnetic moment which is significantly smaller than that of a free Ho ³⁺ ion. The magnetic moment reduction and the imperfect paramagnetic behavior of Ho@C ₈₂ are ascribed to the carbon cage crystal field effect, the partial hybridization of the orbitals of the entrapped Ho atom and the carbon cage, and the interactions between the metal centers.
