| 中文摘要 | The antiferromagnetic phenomena of the Mn-F-Mn spin cluster in KZnF3:Mn2+ and KMgF3:Mn2+ systems have been studied based on the Girerd-Journaux-Kahn (GJK) model and the Heitler-London (HL) model respectively. For the Mn ... Mn distance R in the range 3.4 < R < 4.6 Angstrom, the values of the exchange interaction parameter J calculated with the GJK model are greater by a factor 2 similar to 3 than those with the HL model and the results of J(GJK) are in good agreement with the experimental findings. This means that the contribution of the excited charge-transfer configuration (CTC) is considerably important and the main physical mechanism of the antiferromagnetic characteristics in KZnF3:Mn2+ and KMgF3:Mn2+ can be attributed to the combined effect of the direct exchange and the superexchange interactions.
