摘要：

Polarised neutrons have been used to solve the existing ambiguities in the chemical and magnetic structures of NiFe2O4. The results show conclusively that it has a completely inverted spinel structure with an oxygen parameter of 0.2573 ±0.0003. The observed magnetic moments at room temperature show that nickel ferrite exhibits the Neel ferrimagnetism with m(A)Fe = 4.86μB, m(B)Fe = 4.73μB and m(B)Ni = 2.22μB leading to a net moment of 2.09μB. The Debye-Waller temperature correction was determined with the constant B = 0.8 × 10-16 cm2. © 1969.
