Magnetic properties and giant magnetoimpedance in amorphous and nanocrystalline microwires

We studied magnetic properties and GMI effect of Finemet-type FeCuNbSiB microwires. We observed that GMI effect and magnetic softness of microwires produced by the Taylor-Ulitovski technique, can be tailored by either controlling magnetoelastic anisotropy of as-prepared FeCuNbSiB microwires or controlling their structure by heat treatment or changing the fabrication conditions. GMI effect has been observed in as-prepared Fe-rich microwires with nanocrystalline structure.This work was supported by EU ERA-NET programme under project "SoMaMicSens" (MANUNET-2010-Basque-3), by Spanish MICINN under project MAT2010-18914, by the Basque Government under Saiotek-12 MEMFOMAG project (S-PE12UN139) and by federal target program "Scientific and scientific-pedagogical personnel of innovative Russia", state contract no 14.R18.21.0762.

Giant magnetoimpedance effect in nanocrystalline microwires

We studied GMI effect and magnetic properties of Finemet-type FeCuNbSiB microwires. We observed that GMI magnetic field and frequency dependences and magnetic softness of composite microwires produced by the Taylor-Ulitovski technique can be tailored either controlling magnetoelastic anisotropy of as-prepared FeCuNbSiB microwires or controlling their structure by heat treatment or changing the fabrication conditions. GMI effect has been observed in as-prepared Fe-rich microwires with nanocrystalline structure.This work was supported by EU ERA-NET programme under project "SoMaMicSens" (MANUN ET-2010-Basque-3), by EU under FP7 "EM-safety" project, by Spanish Ministry of Science and Innovation, MICINN under Project MAT2010-18914, by the Basque Government under Saiotek 11 MICMAGN project (S-PE11UN087) and by federal target program "Scientific and scientific-pedagogical personnel of innovative Russia", state contract No. 14.18.21.0783

Developmental peculiarities of nobles’ estates on the territories of distant uyezds in St. Petersburg province

The research is devoted to studying the prerequisites for occurrence, development peculiarities and the distinctive characteristics of nobles’ estates located in the territories of distant uyezds of the St. Petersburg province. Such presentable estates have a number of characteristics that are distinctive from ordinary noble estates. The following are considered as examples: Rapti estate in Luzhskii, Kotly estate in Yamburgskii, Volyshovo estate in Gdovskii, Pokrovskoe estate in Novoladozhskii districts. The studies of previous years affecting the manor housing of the Leningrad Region are analyzed in order to determine the knowledge level on the topic

Estates of the highest nobility in remote districts of St. Petersburg province in the 18th– early 20th century

The article presents the main results of an academic degree research work devoted to remote countryside estates of the aristocracy as special manorial properties, their identification, analysis, preservation, and adaptation for re-use, taking into account scientifically substantiated unique features of this type of objects. The contents of the main chapters are briefly summarized, and the principal conclusions are given
