IR Thermographic System Supplied with an Ordered Fiber Bundle for Investigation of Power Engineering Equipment and Units
In this article, the authors propose an IR imaging system, supplied with an IR bundle of ordered silver halide fibers, for the acquisition of 2D temperature field distribution in hard-to-reach places. We assessed crosstalk between neighboring individual fibers of the bundle, carried out calibration of the IR imaging system, and determined modelled defects using this system. The results showed the applicability of the system for the inspection and investigation of power engineering units.

Frequency and Magnetic Field Dependence of the Skin Depth in Co-rich Soft Magnetic Microwires
We studied giant magnetoimpedance (GMI) effect in magnetically soft amorphous Co-rich microwires in the extended frequency range. From obtained experimentally dependences of GMI ratio on magnetic field and different frequencies we estimated the penetration depth and its dependence on applied magnetic field and frequenc

Spin excitations of the correlated semiconductor FeSi probed by THz radiation
By direct measurements of the complex optical conductivity of
FeSi we have discovered a broad absorption peak centered at frequency
that develops at temperatures below 20 K.
This feature is caused by spin-polaronic states formed in the middle of the gap
in the electronic density of states. We observe the spin excitations between
the electronic levels split by the exchange field of . Spin
fluctuations are identified as the main factor determining the formation of the
spin polarons and the rich magnetic phase diagram of FeSi.Comment: 5 pages, 4 figure
