How systems of single-molecule magnets magnetize at low temperatures
J. F. Fernandez, J. J. Alonso
We model magnetization processes that take place through tunneling in crystals of single-molecule magnets, such as Mn_12 and Fe_8. These processes take place when a field H is appl…
Magnetic Tunnel Window's Imprint and Beyond
J. J. Alonso, J. F. Fernandez
We report results from Monte Carlo simulations of systems of magnetic dipoles that relax through quantum tunneling, much as Fe_8 crystals at very low temperature.For short times, a…
Magnetization Process of Single Molecule Magnets at Low Temperatures
J. F. Fernandez, J. J. Alonso
We show that correlations established before quenching to very low temperatures, later drive the magnetization process of systems of single molecule magnets, after a magnetic field…
