Phase separation in paramagnetic Eu0.6La0.4-xSr xMnO3

We investigate the magnetic properties of the system Eu 0.6La0.4-xSrxMnO3 with 0.1≤x≤0.3 by means of magnetic susceptibility and electron spin resonance measurements. Ferromagnetic resonance signals are observed in the paramagnetic regime from above the magnetic ordering temperature TN up to approximately room temperature. This regime is characterized by the coexistence of ferromagnetic entities within the globally paramagnetic phase. The results are compared to the Griffiths scenario reported in La1-xSr xMnO3. © 2011 American Physical Society

Apskaitos ir finansinės atskaitomybės gerinimo problemos ir būdai globalizacijos ir skaitmeninimo sąlygomis

In modern economic conditions, it is impossible for companies and enterprises to operate without accounting and financial reporting. Currently, enterprises in Kazakhstan carry out their activities under international financial reporting standards (IFRS). One of the main reasons for the transition to international standards is the entry of Kazakhstan’s economy onto the international stage. The purpose of this study is to analyse the process of digitalisation of accounting and financial reporting in the context of globalisation of the economy, especially in the field of public administration. Based on the research conducted, the authors aim to elaborate the main ways of developing and improving financial accounting and reporting for the Republic of Kazakhstan. This study applies a comparative approach, structural analysis, synthesis, and classification. In the course of the study, the main goals and objectives of financial accounting at enterprises are considered; the main trends in the development of financial accounting in the context of digitalisation of the economy are analysed; the main problems in organising financial accounting at enterprises are revealed; and the main ways and directions for improving financial accounting at enterprises in the context of economic globalisation are disclosed. It is concluded that the development of financial accounting and reporting is impossible without the development of the information society and the introduction of administrative management in a digitalised environment

Regional transformations in Bulgaria and challenges for sustainable development

Structural changes in rural areas are a subject of widespread discussion. During the transition to a market economy, Bulgarian agriculture underwent serious reforms, and after the accession to the EU, the transformations of the sector became even more significant. Political and socio-economic changes have an impact on agricultural production, organisational structure, and market performance. These processes have played an essential role in the development of rural areas. The aim of the study is based on an analysis of structural changes in Bulgarian agriculture, to outline their impact on the models of transformation of rural areas and make recommendations for sustainable development. Significant changes are observed during the analysed period. The agricultural sector remains polarised and dominated by several significant sub-sectors – cereals and oilseeds. The Common Agricultural Policy (CAP) does not contribute to balanced and sustainable development and deepens disparities. During the new programming period, the opportunities for modelling the CAP are significant and vary considerably. A new conceptual framework needs to be implemented in Bulgaria - the local model related to regional specifics can solve some of the challenges

Their magnetic properties are studied in the temperature range 5–300 K using the magnetic resonance and magnetometry methods. It is found that strontium hexaferrite microinclusions in the (SrFe12O19)0.05(CaCu3Ti4O12)0.95 composite “magnetize” CaCu3Ti4O12 at temperatures from 300 to 200 K, forming a ferrimagnetic particle near the SrFe12O19 “core.” The magnetic resonance line below 200 K splits into two lines corresponding to SrFe12O19 and CaCu3Ti4O12. The core effect decoration is manifested in the increase in the Curie–Weiss temperature from 25 K in CaCu3Ti4O12 without the doping ceramics to 80 K in the composite with 5% of SrFe12O19
