چکیده

The article describes electromagnetic and microwave properties of the polymer composite with lithium spinel ferrite inclusion composition Li 0.33 Fe 2.29 Zn 0.21 Mn 0.17 O 4 in frequency range 100-7000 MHz. It is shown that samples a mass fraction 60, 80% have pronounced radio-absorbing properties, measured using reflection coefficient on metal plate (return losses). For ferrite, minimum return loss was -37.5 dB at 2.71 GHz an absorption width -10 3 GHz. High characteristics are directly related to use ferroelectric P(VDF-TFE) as binder, which expressed combined action mechanisms magnetic phases. Keywords: composite, polyvinylidene fluoride, material.

"EXAFS and EPR analysis of the local structure of Mn-doped Li 2 B 4 O 7 " (2013). Peter Dowben Publications. 264. The local structure of Mn-doped Li 2 B 4 O 7 (001) was investigated using extended X-ray absorption fine structure (EXAFS) at the Mn K edge and electron paramagnetic resonance (EPR). The location of the Mn dopant in a lithium tetraborate crystal is consistent with occupation of a si...
