单分子磁性的警告：非线性Arrhenius图
A Caveat for Single-Molecule Magnetism: Non-linear Arrhenius Plots
摘要：
Mn 12单分子磁体（SMM）的磁化弛豫不遵循简单的阿克里尼乌斯定律，即使对于在低频（5-1500 Hz）下收集的数据也是如此，这是由于经由具有更大热势垒但更快的尝试速率的激发态的弛豫路径的贡献。提出了一种修正的Arrhenius方程作为一种手段，以克服这个问题，并获得一个更可靠的极限值与地面S=10状态相关的磁化弛豫的障碍。
英文摘要：
The magnetization relaxation of Mn12 single-molecule magnets (SMMs) does not follow a simple Arrhenius law, even for data collected at low frequencies (5-1500 Hz) due to contributions from relaxation pathways via excited states with larger thermal barriers, but much faster attempt rates. A modified Arrhenius equation is presented as a means to overcome this problem and obtain a more reliable limiting value for the barrier to magnetization relaxation associated with the ground S=10 state.
