(Сибирский федеральный университет. Siberian Federal University, 2018-03)We describe the conditions of existing periodic part in Shunkov group -
Crystallization Kinetics and Magnetic Properties of Fe₈₀₋ₓCoₓP₁₄B₆ Metallic Glasses
(Сибирский федеральный университет. Siberian Federal University, 2018-03)We report about formation mechanism, crystallization kinetics and magnetic properties observed in the series of rapidly solidified Fe₈₀₋ₓCoₓP₁₄B₆ metallic glasses with x = 25, 32, 35 and 40 at.%. Magnetic soft Fe₈₀₋ₓCoₓP₁₄B₆ ... -
On some Sufficient Condition for the Equality of Multi-clone and Super-clone
(Сибирский федеральный университет. Siberian Federal University, 2018-03)Multi-clones and super-clones are considered in this paper. They are generalizations of clones. To get a super-clone one need to add to a multi-clone the closure condition with respect to solvability of the simplest ... -
Effect of the Spin-orbit Coupling and Impurity Scattering on the Spin Resonance Peak in Three-orbital Model for Fe-based Superconductors
(Сибирский федеральный университет. Siberian Federal University, 2018-03)Here we study a combined effect of the spin-orbit coupling and scattering on the nonmagnetic disorder on the formation of the spin resonance peak in iron-based superconductors. Spin susceptibility is calculated within ... -
On Holomorphic Continuation Integrable Functions of Along Finite Families of Complex Lines in n-circular Domain
(Сибирский федеральный университет. Siberian Federal University, 2018-02)The paper consider, a family of complex lines passing through the final (n+1) the number of points lying in the n-circled field D in Cn and f integrable on the boundary -
On Applications of the Cayley Graphs of some Finite Groups of Exponent Five
(Сибирский федеральный университет. Siberian Federal University, 2018-02)Let B0(2; 5) be the largest two–generator finite Burnside group of exponent five. It has the order 534. We define an automorphism φ which translates generating elements into their inverses. Let CB0(2;5)(φ) be the centralizer ... -
Multidimensional Boundary Analog of the Hartogs Theorem in Circular Domains
(Сибирский федеральный университет. Siberian Federal University, 2018-02)This paper presents some results related to the holomorphic extension of functions, defined on the boundary of a domain D Cn, n > 1, into this domain. We study a functions with the one-dimensional holomorphic extension ... -
On a Question about Generalized Congruence Subgroups
(Сибирский федеральный университет. Siberian Federal University, 2018-02)Elementary net (carpet) δ = (δ ij) is called admissible (closed) if the elementary net (carpet) group E(δ) does not contain a new elementary transvections. This work is related to the problem proposed by Y.N.Nuzhin in ... -
Boundary Morera Theorem for the Matrix Ball of the Third Type
(Сибирский федеральный университет. Siberian Federal University, 2018-02)In the article we consider a boundary version of Morera’s theorem for the matrix ball of the third type -
Bilayer Magnetic Structures with Dipolar Interaction
(Сибирский федеральный университет. Siberian Federal University, 2018-02)Computer simulation of bilayer structures with dipolar interlayer interaction was performed. Equilibrium properties were considered for systems with various thicknesses of magnetic layers and distances between the layers. ... -
Morera’s Theorem and Functional Series in the Class of A-analytic Functions
(Сибирский федеральный университет. Siberian Federal University, 2018-02)The aim of this paper is to investigate A-analytic functions in a special case when the function A is an anti-analytic function in a domain. We prove that a continuous function satisfying the integral condition of the ... -
Compact Microwave Power Limiter with HTSC Element
(Сибирский федеральный университет. Siberian Federal University, 2018-02)A design of microwave power limiter having a structure of three-pole microstrip filter is developed. In the device outer resonators are coupled through an inner resonator containing high-temperature super- conducting ... -
