On the height of the magnetic anisotropy barrier — •Claudia Martin and Jens Kortus — TU Bergakademie Freiberg, Fakultät für Chemie und Physik
We will present a systematic study of the influence of the magnetic ground state S on the magnetic anisotropy D for a family of Mn6 compounds. We have been able to show that the system can either minimize S or D. Furthermore, our results indicate that the barrier U=S2|D| is nearly constant for the investigated range of possible ground states S. Interestingly the highest barrier is observed for the lowest ground states S while the high spin ground state yields the lowest barrier, which we will also comment on.
