The possibility to use the Au(1 0 0)/Fe(1 0 0)/MgO(1 0 0) system as a substrate for future spin-polarized transport measurements on Mn12 single molecule magnets has been investigated by means of scanning tunneling microscopy and X-ray photoelectron spectroscopy at room temperature. In particular, the stability of the iron layer during a wet chemical preparation of Mn12 monolayers was studied. The results demonstrate that Mn12 can be deposited on Au(1 0 0)/Fe(1 0 0)/MgO(1 0 0) while preserving the metallic nature of the ferromagnetic iron layer which is required as a possible source of spin-polarized electrons in future studies. 相似文献

We investigate the beam energy dependence of neutron and proton squeeze-out in collisions of197Au+197Au atE/A=400—800 MeV. The azimuthal anisotropy that describes the enhanced emission of mid-rapidity neutrons perpendicular to the reaction plane rises strongly with the transverse momentum of the neutrons. This dependence of the azimuthal anisotropy follows a universal curve — independent of beam energy — if the neutron momenta are measured in fractions of the projectile momentum per mass unit. Analogously, the kinetic energy spectra of mid-rapidity neutrons exhibit a universal behaviour as a function of the kinetic energy of the projectile.

The branching ratios of the beta-decay of12B and12N to the 4.44 MeV state in12C were determined by (βγ-coincidences to be (1.182±0.019)% and (1.898±0.032)% of the total rate, resp. This givesft ?=(1.407±0.023) · 105 s andft +=(1.406±0.024) · 105 s. For theft-asymmetryδ=(ft +/ft ?)?1 the valueδ=?(1±14) · 10?3 was obtained. This is in contrast to other GT mirror transitions which show positiveδ of a few percent. 相似文献
