PARAMAGNETIC BEHAVIOR OF Nd₂Fe₁₄B SINGLE CRYSTAL

The paramagnetic parameters of the Nd₂Fe₁₄B single crystal were measured. In the temperature range from about 600K to 830K, the temperature dependence of the reciprocal susceptibility obeyed Curie-Weiss law, from which the effective magnetic moment for Fe atoms, 3.97μ_B/Fe atom, can be obtained.
