Effects of uniaxial pressure on the quantum tunneling of magnetization in a high-symmetry Mn12 single-molecule magnet
James H. Atkinson, Adeline D. Fournet, Lakshmi Bhaskaran +6
The symmetry of single-molecule magnets dictates their spin quantum dynamics, influencing how such systems relax via quantum tunneling of magnetization (QTM). By reducing a system'…
A Microscopic and Spectroscopic View of Quantum Tunneling of Magnetization
Junjie Liu, Enrique del Barco, Stephen Hill
This chapter takes a microscopic view of quantum tunneling of magnetization (QTM) in single-molecule magnets (SMMs), focusing on the interplay between exchange and anisotropy. Care…
Magnetic Quantum Tunneling: Insights from Simple Molecule-Based Magnets
Stephen Hill, Saiti Datta, Junjie Liu +7
This article takes a broad view of the understanding of magnetic bistability and magnetic quantum tunneling in single-molecule magnets (SMMs), focusing on three families of relativ…
Magnetic anisotropy in thin films of Prussian blue analogues
D. M. Pajerowski, J. E. Gardner, M. J. Andrus +6
The magnetic anisotropy of thin (~ 200 nm) and thick (~ 2 m) films and of polycrystalline (diameters ~ 60 nm) powders of the Prussian blue analogue RbNi[Cr(CN)$_…
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…
Comment on "Influence of Dzyaloshinskii-Moriya Exchange Interaction on Quantum Phase Interference of Spins"
E. del Barco, S. Hill, D. N. Hendrickson
In a recent Letter [1], Wernsdorfer et al. report an experimental study of a Mn12 molecular wheel which shows essentially identical behavior to the Mn12 wheel studied by Ramsey et…
Reply to Wernsdorfer's post: "Correspondence on: Quantum interference of tunnel trajectories between states of different spin lenght in a dimeric molecular nanomagnet"
Christopher M. Ramsey, Enrique del Barco, Stephen Hill +3
We present here an exact version of our response (dated April 27) to Wernsdorfer's correspondence submitted to Nature Physics on March 31, 2008. After consultation with a referee,…
Limitations of the Giant Spin Hamiltonian in Explaining Magnetization Tunneling in a Single-Molecule Magnet
A. Wilson, J. Lawrence, E-C. Yang +3
EPR studies of a Ni4 single-molecule magnet yield the zero-field-splitting (zfs) parameters, D, B40 and B44, based on a giant spin approximation (GSA) with S = 4. Experiments on an…
