Special Issue Information

Dear Colleagues, 

Nanoscience has undergone surging development in recent decades with a simultaneous transition of scientific results to innovative technologies which in turn enrich and expand the potentialities of nanoscience and nanotechnology. The numerous interdisciplinary applications range from energy and electronics to medicine and industry. The backbone of the whole process, from synthesis to specific applications, is material characterization to probe the specific characteristics and qualities of materials and devices. Both standalone and combined, various methods provide an insight to structural or compositional information, such as the shape, size, crystal structure, chemical composition, surface or interface environment, as well as physicochemical responses which can be, among others, optical, electrical, or magnetic.

This Special Issue on “Characterization of Nanostructure Materials” aspires to present the various characterization methods and capabilities which emerge through their application to the broad spectrum of nanotechnology.

In order to broaden the application of nanocrystalline soft magnetic materials in electrical engineering under extreme conditions, nanocrystalline alloys must also have good characteristics under high-frequency and nonsinusoidal excitation. In this paper, the magnetic properties of Fe-based nanocrystalline alloys excited by high repetition frequency pulses were measured. Excitation frequency and duty cycles are two important factors in the study of magnetic properties under pulse excitation. With the amplitude of the pulse remaining constant, different local hysteresis curves were obtained by changing the frequency and duty cycle. The experimental results proved that the higher the frequency is and the smaller the duty cycle is, the narrower the local hysteresis loop is. Finally, the finite element method (FEM) was used to model the magnetic core coupling with an impulse circuit based on the measured magnetic properties. Compared with the experimental results, the simulation results showed that the field-circuit coupling analysis model can effectively reflect the influence law of the frequency and duty cycle on magnetic properties.
