    摘要: Heavy-fermion compound CeAl2 has a Kondo temperature TK of 5 K and a /Neel temperature TN of 3.8 K. As the dimensions of specimen decrease, the size effect was shown as the suppression of TK and the magnitude of anti-ferromagnetic anomaly in specific heat. For 80Å nanoparticles the magnitude of /γ extrapolates to 9500mJ/K2 mole at absolute zero, whose value falls in the highest range ever reported for heavy-fermion systems.
