摘要：

We calculated the magnetization of small ferromagnetic particles with uniaxial anisotropy. The numerical data were compared with experimental results for a magnetic liquid consisting of small amorphous Fe0.75C0.25 particles in decalin. From the comparison an anisotropy constant K congruent-to 3 x 10(5) J m-3 was estimated.
