An approach for the investigation of vortex core switching is presented. Thermal effects up to the Curie point are included in a micromagnetic framework based on the recently developed Landau-Lifshitz-Bloch equation. In this approach it is easier to avoid numerical discretization artifacts, commonly present when a Bloch point is mediating the switching process. Switching in thin circular permal...

The electron-beam-pumped XeF laser operating on the B-X and C-A transitions shows a strong temperature dependence. Fluorescence, gain, and laser output measurements in Ar/Xe/NF3 and Ne/Xe/NF3 mixtures are reported for temperatures from 300 to 600 K. Elevated temperatures cause stronger mixing between the Band C states as well as among the vibrational levels within the B state. Together with the...
