Surface Influence on Flux Penetration into HTSBulks
The influence of surface treatment on AC loss in melt-processed quasi-single crystal HTS was investigated with resonance oscillations technique. We have found that amplitude dependencies of AC loss on magnetic field amplitude become rather complicated after surface polishing. The experimental data show well distinguished dynamic crossover from absence of barrier at low rates of field variation ...

متن کاملBoundary and finite-size effects in small magnetic systems
We study the effect of free boundaries in finite magnetic systems of cubic shape on the field and temperature dependence of the magnetisation within the isotropic model of D-component spin vectors in the limit D → ∞. This model is described by a closed system of equations and captures the Goldstone-mode effects such as global rotation of the magnetic moment and spin-wave fluctuations. We have o...
متن کاملFinite size effects in patterned magnetic permalloy films
Electron beam lithography has been used to prepare 250-Å-thick square-shaped permalloy dots whose width and separation are in the range between 1 and 4 mm. The static and dynamic magnetic properties of these structures have been investigated by complementary techniques such as magneto-optic Kerr effect ~MOKE!, magnetic force microscopy ~MFM!, and Brillouin light scattering ~BLS!. Longitudinal M...
