On the anisotropy barrier reduction in fast relaxing Mn12 single-molecule magnets
Stephen Hill, Muralee Murugesu, George Christou
A novel angle-swept high-frequency EPR (HFEPR) technique is described that enables in-situ alignment of single-crystal samples containing low-symmetry magnetic species such as sing…
A Caveat for Single-Molecule Magnetism: Non-linear Arrhenius Plots
Christos Lampropoulos, Stephen O. Hill, George Christou
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 contributi…
Manifestation of Spin Selection Rules on the Quantum Tunneling of Magnetization in a Single Molecule Magnet
J. J. Henderson, C. Koo, P. L. Feng +5
We present low temperature magnetometry measurements on a new Mn3 single-molecule magnet (SMM) in which the quantum tunneling of magnetization (QTM) displays clear evidence for qua…
