2001. 11. 16. This behavior is highly sensitive to the applied magnetic fields (H); in larger magnetic fields, e.g., H = 5 Oe, the difference between the ZFC and FC magnetizations is undetectable. Even at a relatively low magnetic field, H = 5 Oe, the large values of μ eff ≈ 8000 give μ eff H / k B ≈ 2.7 K, which is within the range of blocking temperatures.

The magnetic behaviour is different in the two inequivalent crystallographic Ce sites, namely, the magnetic moment on the high-symmetry site reaches the ordered value of ∼2 μ B at relatively high temperatures, while the magnetic moment on the low-symmetry site increases slowly with temperature lowering and reaches a reduced value of ∼1 μ B at 1.5 K.
