Magnetization reversal through synchronization with a microwave

Z. Z. Sun, X. R. Wang
2006 Physical Review B  
Based on the Landau-Lifshitz-Gilbert equation, it can be shown that a circularly-polarized microwave can reverse the magnetization of a Stoner particle through synchronization.  ...  A microwave needs only to overcome the energy dissipation of a Stoner particle in order to reverse magnetization unlike the conventional method with a static magnetic field where the switching field must  ...  Its motion is very complicated, corresponding to a nonsynchronized motion. It is found that whether the motion is synchronized or not is sensitive to the microwave frequency.  ...

Normal modes for specific motions of macromolecules: application to the hinge-bending mode of lysozyme

B. Brooks, M. Karplus
1985 Proceedings of the National Academy of Sciences of the United States of America  
Application of the method to the interdomain (hingebending) motion of lysozyme yields a frequency of 3.6 cm-'. This is similar to the value obtained from earlier adiabaticenergy-minimization studies.  ...  Analysis of the mode shows that the relaxation associated with the hinge bending is highly delocalized; that is, the dihedral angle and energy changes are distributed over many residues, including some  ...  not directly involved in domain-domain contacts or hinge region may deviate significantly from the motions resulting from the adiabatic energy-minimization procedure.  ...
