Abstract
A new single-molecule magnet [Mn11Fe1O 12(CH3COO)16(H2O) 4].2CH3COOH.4H2O (Mn11Fe 1) has been synthesized. The structure has been studied by the single crystal x-ray diffraction. The difference of Jahn-Teller distortion between Fe3+ and Mn3+ ion reveals that Fe3+ ion substitutes for Mn3+ ion on the Mn(3) sites in the Mn 12 skeleton. The temperature dependence of the magnetization gives a blocking temperature TB≤1.9K for Mn11Fe1. Based on the magnetization process analysis of the crystal at T≤2K, we suggest that Mn11Fe1 has the ground state with a total spin S≤ 11/2.
