The magnetic Jahn-Teller effect in half-integer spin triangles: static or dynamic?
07/21/2017 - 16:14
The so-called "magnetic Jahn-Teller effect" has been postulated for several years now to explain the lifting of the ground-state degeneracy in half-integer antiferromagnetic spin triangles.
We tried to assess its nature in the highly symmetric [Fe3O(O2CPh)6(py)3]ClO4·py using SQUID magnetometry and EPR spectroscopy.
You can read more at our recent article in Inorg. Chem., 2017, 56, 762-772, and get an idea of a dynamic spin Hamiltonian we used by looking at the short video below:
