some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Magnetic and structural properties and crystallization behavior of Si-rich FINEMET materials

The magnetic and structural properties of an Si-rich grade FINEMET alloy with a composition of Fe73.5Si16.1B6.4Nb2.9Cu1.1 in at% [Fe82.7Si9.1B1.4Nb5.4Cu1.4 (wt%)] were investigated after primary and secondary crystallization of ribbon samples. Optimally annealed ribbons exhibited a homogeneous microstructure composed of B7 nm DO3 nanocrystals surrounded by the retained amorphous phase. This is ...

Magnetic Properties and Crystallization Kinetics of a Mn-Doped FINEMET Precursor Amorphous Alloy

The kinetics of nanocrystallization of a Mn-doped FINEMET alloy from its amorphous precursor is reported. The alloy studied was of a composition (Fe1 Mn )73 5Nb3CuSi13 5B9 where = 0 05. X-ray diffraction (XRD) confirmed that -FeSi is the product of primary nanocrystallization. Crystallization kinetics were studied using time-dependent magnetization, ( ), as a measure of the volume fraction crys...
