Opis:: Room temperature ferromagnetic properties of Zn-Mn-O show evident dependence on manganese concentration and preparation conditions. We systematically studied series of samples with manganese concentration ranging from 0 to 10 at.%, prepared in air at thermal treatment temperatures ranging from 400 to 900°C. The samples were investigated by X-ray diffraction, TEM, magnetization measurements and XPS spectroscopy. XPS analyses of surface composition, chemical bonding and XPS depth profiling were successfully employed on powder revealing the chemical composition at the surface of the grains and underneath. The study emphasizes important role of the grain surface in observed room temperature ferromagnetism. It seems that the ferromagnetic phase is correlated with oxygen build up at the surface.

Opis:: The ethnic structure of Vojvodina (North Serbia) has affected the formation of diverse gastronomy. Inhabitants with their own gastronomic characteristics have helped it to become a favourable destination for the development of tourism focusing on food. Alongside with thirty nations who inhabit Vojvodina, a large number of Hungarian inhabitants highlighted the need for the research of production and preparation of authentic food in households within this ethnic group in terms of its significance for the development of food tourism in rural areas. The subject of the paper is the manner of nutrition of Hungarians who inhabit rural areas in Vojvodina, in terms of its significance for the development of food tourism. The aim of the paper is to research the level of preserved authenticity of their gastronomy, as a possibility for authentic gastronomic experience of tourists. The aim of this research by phases is to determine what kinds of agricultural crops and livestock is grown, as well as which authentic products are produced and to which extent traditional Hungarian dishes are prepared, then how well they are preserved and whether there are any differences compared to their compatriots.

Opis:: Spin dynamics of nanoparticle $La_{0.7}Ca_{0.3}Mn_{0.7}Fe_{0.3}O_3$ system was studied through the set of diverse magnetic measurements. Analysis of the data obtained from magnetic relaxation measurements, memory effect and AC susceptibility experiments pointed to a spin glass like behavior of interacting nanoparticle system.

Opis:: Nanoparticle $La_{0.7}Ca_{0.3}Mn_{0.7}Fe_{0.3}O_3$ with the average particle size of 10 nm was mechanochemically synthesized in the single-step procedure. Temperature and field dependences of magnetization were recorded under both ambient and applied hydrostatic pressure up to 0.47 GPa. At ambient pressure, two magnetic transition points were observed: one of the spin-glass like type at the temperature $T_{f}$ ≈ 34 K, and ferro-to-paramagnet transition at $T_{C}$ ≈ 51 K. Under the applied pressure magnetic parameters gradually changed: (i) both $T_{C}$ and $T_{f}$ were lowered with the increase in pressure; (ii) both high field magnetization $M_{5T}$ and remanent magnetization $M_{Rem}$ decreased with pressure; (iii) coercivity $H_{C}$ increased with pressure. The obtained results show that magnetism of a nanoparticle system with high degree of intrinsic disorder diminishes with the applied pressure that is in compliance with the effect of the increased cationic disorder ("internal pressure") in bulk manganites.
