Title: Kapitza problem for the magnetic moments of synthetic antiferromagnetic systems

Abstract

The dynamics of magnetization in synthetic antiferromagnetic systems with the magnetic dipole coupling in a rapidly oscillating field has been examined. It has been revealed that the system can behave similar to the Kapitza pendulum. It has been shown that an alternating magnetic field can be efficiently used to control the magnetic state of a cell of a synthetic antiferromagnet. Analytical relations have been obtained between the parameters of such an antiferromagnet and an external magnetic field at which certain quasistationary states are implemented.

  • The magnetic properties of double tunnel junctions with perpendicular anisotropy were investigated. Two synthetic antiferromagnetic references are used, while the middle storage magnetic layer can be either a single ferromagnetic or a synthetic antiferromagnetic FeCoB-based layer, with a critical thickness as large as 3.0 nm. Among the different achievable magnetic configurations in zero field, those with either antiparallel references, and single ferromagnetic storage layer, or parallel references, and synthetic antiferromagnetic storage layer, are of particular interest since they allow increasing the efficiency of spin transfer torque writing and the thermal stability of the stored information as compared to single tunnel junctions.more » The latter configuration can be preferred when stray fields would favour a parallel orientation of the reference layers. In this case, the synthetic antiferromagnetic storage layer is also less sensitive to residual stray fields.« less
  • The existence of magnetic moments of neutrinos points to physics beyond the standard model. Given current upper limits, terrestrial measurements are difficult or completely unfeasible. However, estimates of transition moments can be obtained from observation of objects such as active galactic nuclei (AGN) by means of neutrino telescopes. We describe the way of estimating the magnitudes of transition moments from such observations.
  • The Brueckner theory predicts corrections to the shell model moments of even such simple nuclei as N/sup 15/, O/sup 17/, and K/sup 39/. Calculation is difficult because of the many states excited by the model operator. To obtain some notion of orders of magnitude a simple model is exaniined in which the core is represented by a uniform Fermi gas; the summations then become integrals in momentum space. lt is assumed, as is usual in shell model work, that the effective two-body potential can be crudely represented by a static central potential with exchange. The second order corrections are foundmore » to be of the same order of magnitude as, but somewhat smaller than, the effect in first order of the usual space-exchange current. (auth)« less
