The Contribution of Hot Electron Spin Polarization to the Magnetotransport in a Spin-Valve Transistor at Finite Temperatures

The effect of spin mixing due to thermal spin waves and temperature dependence of hot electron spin polarization to the collector current in a spin-valve transistor has been theoretically explored. We calculate the collector current as well as the temperature dependence of magnetocurrent at finite temperatures to investigate the relative importance of spin mixing and hot electron spin polarization. In this study the inelastic scattering events in ferromagnetic layers have been taken into account to explore our interests. The theoretical calculations suggest that the temperature dependence of hot electron spin polarization has substantial contribution to the magnetotransport in the spin-valve transistor.Comment: 8 pages and 6 figure

Socio economic profile of direct seeded rice (DSR) farmers of Haryana

The study has focused on socio economic profile, adoption level of Direct seeded rice (DSR) farmers and extension strategy to increase the adoption of DSR cultivation in Haryana (India). More than half of respondents (51.66 %) belonged to the middle age group 36-50 years and maximum 21.67 per-cent farmer qualification found metric. Majority of the farmers (50.83 per cent) had low level of socio-economic. Economic motivation of farmers was 70.83 per cent belonged to low to moderate level, whereas 67.5 per-cent of respondents belonged moderate to high innovation proneness. The overall adoption level of DSR technology was low to moderate, since 70 per-cent of respondents belonged to low to medium category

Prospects of Citrus sinensis (masumbi) cultivation in Haryana State, India

The empirical study on prospects of Citrus sinensis cultivation by farmers indicated that overall prospects of masumbi (C. sinensis) crop were medium to high since 77.5% respondents belonged to these categories. Majority of respondents agreed that better market facilities (weighted mean score 2.72), increased purchasing power of people (2.65), better fruit quality (2.62), better economic return (2.53) and increase in demand of fruit were the major prospective aspects for its wider adoption (2.53), whereas better technical support (1.20) and better credit facilities (1.08) both were not up to the desired level as expressed by the farmers. So the government should make concerted efforts to further strengthen the highly prospective aspects like better marketing facilities, cultivars of better quality fruits at farm gate or village level. On the basis of result obtained, the prospects of masumbi (C. sinensis) cultivation may be high in future
