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 susceptibility of ~Sm0.65Sr0.35!MnO3 shows an unusual temperature dependence above the Curie temperature which is attributed to the presence of small manganese-ion clusters with S'9. A field-induced transition is observed in the paramagnetic state, which corresponds to a doubling of the cluster size and an increase of the strength of the interaction between them. The continuous transition f...

Abstract Direct attachment of piezoelectric transducers on hot targets raise formidable challenges as piezoelectric materials will lose their piezoelectric characteristic at elevated temperature due to Curie temperature limitation. In this paper, an attempt was made to build an integrated probe for hot target which enables to alleviate innovatively the Curie temperature limitation. In addition,...
