AB  - Nanocrystalline nickel manganite (NiMn2O4) was obtained by sol-gel combustion using glycine as fuel, followed by calcination at 800°C. X-ray diffraction (XRD) analysis confirmed the formation of a pure cubic spinel structure with a crystallite size of 54.5 nm. Scanning electron microscopy (SEM) of the obtained nickel manganite powder showed porous nanocrystalline morphology. The material constant (B) of the obtained nickel manganite powder applied as paste and dried at 100°C was determined as 4812 K in the temperature range 20-50°C, confirming potential application in flexible temperature sensors.

AB  - The chemical synthesis of nickel manganite powder was performed by a complex polymerization method (CPM). The obtained fine nanoscaled powders were uniaxially pressed and sintered at different temperatures: 1000-1200 degrees C for 2 h, and different atmospheres: air and oxygen. The highest density was obtained for the sample sintered at 1200 degrees C in oxygen atmosphere. The energy for direct band gap transition (Eg) calculated from the Tauc plot decreases from 1.51 to 1.40 eV with the increase of the sintering temperature. Indentation experiments were carried out using a three-sided pyramidal (Berkovich) diamond tip, and Young's modulus of elasticity and hardness of NTC (negative temperature coefficient) ceramics at various indentation depths were calculated. The highest hardness (0.754 GPa) and elastic modulus (16.888 GPa) are exhibited by the ceramics sintered at highest temperature in oxygen atmosphere.

AB  - This brief presents the transport parameters of silver layers on a polyimide substrate fabricated by an inkjet printing technology using nanoparticle inks with 20 wt% and 40 wt% silver. All the electrical characteristics of the samples were measured by Hall effect measurement system at 0.37 T. The electron mobility in inkjet printed silver layer was 7.07 and 4.58 cm(2)/V s for 20 wt% silver, 29.6 and 21.3 cm(2)/V s for 40 wt% silver at 77 and 300 K, respectively. The resistivity in inkjet printed silver layer with 20 wt% is 20.6 x 10(-6) and 27.1 x 10(-6) Omega cm, and 4.81 x 10(-6) and 8.27 x 10(-6) Omega cm for 40 wt% silver at 77 and 300 K, respectively. The surface morphology and profiles of the samples were obtained with an atomic force and scanning electron microscope.

AB  - Nickel manganite powder synthesized by calcination of a stoichiometric mixture of manganese and nickel oxide was additionally mechanically activated in a high energy planetary ball mill for 5-60 min in order to obtain a pure NiMn2O4 phase. The as-prepared powders were uniaxially pressed into disc shape pellets and then sintered for 60 min at 1200 degrees C. Changes in the particle morphology induced by mechanical activation were monitored using scanning electron microscopy, while changes in powder structural characteristics were followed using X-ray powder diffraction. The ac impedance spectroscopy was performed on sintered nickel manganite samples at 25 degrees C, 50 degrees C and 80 degrees C. It was shown that mechanical activation intensifies transport processes causing a decrease in the average crystallites size, while longer activation times can lead to the formation of aggregates, defects and increase of lattice microstrains. The observed changes in microstructures were correlated with measured electrical properties in order to define optimal processing conditions.

AB  - This paper explores an influence of conductive layer geometry on electrical parameters of ferrite electromagnetic interference (EMI) suppressor, which consists of conductive layer in ferrite monolithic structure. Near ferrimagnetic resonant frequency, component has maximal impedance and efficiently suppresses noise. In order to achieve better suppression (i.e., larger impedance), conductive layers should be longer. Nevertheless, longer conductive lines introduce parasitic capacitance, which causes the maximal impedance frequency shift. Because of that, the frequency range where component can be used for efficient EMI suppression is shifted towards lower frequencies, and designing process should be very careful. In this paper, we present simulation of frequency dependent impedance for different geometry parameters of conductive layer. Results for the inductance and the maximal impedance frequency shift of the proposed EMI suppressors are presented in the range 1 MHz-3 GHz. Proposed EMI suppressors were experimentally tested using Agilent 4287A RF LCR meter. Comparison of simulated and measured values of impedance shows a good agreement.

AB  - Intrinsic resistivity and carrier transport parameters of sintered nickel manganite samples (NTC thermistor grade) were determined using a Hall effect measurement system based on the van der Pauw method. Powder mixtures composed of MnO, NiO and with small amounts of CoO and Fe(2)O(3) were free surface energy activated by milling in an ultra fast planetary mill for 5, 15, 30, 45 and 60 min. The powders were uniaxially pressed with 196 MPa into discs and sintered at 1200 A degrees C for 60 min. Full characterization of nickel manganite samples was done using SEM, EDS and XRD analysis. The Hall effect was measured at different temperatures (room temperature, 50, 80, 100 and 120 A degrees C) with an applied field of 0.37 T and also 0.57 T at room temperature. The activation energy E (a) (energy of conduction) and the coefficient of temperature sensitivity B (25/80), were calculated from measured resistivity values. The measured mobility, resistivity/conductivity, U-I plots, and Hall coefficients were mutually compared and correlated versus microstructure development and macroscopic parameters such as the powder activation time and ambient temperature.
