Hall coefficient of bismuth single crystal doped with gallium has been measured in the temperature range 100 - 300K for different magnetic field strengths. Gallium is an element of group III and so it should act as an acceptor impurity to bismuth. The Hall coefficient is expected to be positive. However, the coefficient is observed to have negative sign in most cases. Change of sign of the coefficient is also observed for higher magnetic field strengths.

Student, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India Kesar Chayal  Assistant Professor, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India The present study was an attempt to investigate the preference of information sources by agriculture farmers. Study was conducted in Jaipur district of Rajasthan. 75 respondents were selected through random sampling method for the study and personal interview technique was used for data collection. Data related to information source used by the farmers revealed that mobile phone was the most preferred source by the farmers (70.66%). Farming helping apps (56%), television (53.33%), internet (52%) and local leader /neighbors (41.33%) always used by the farmers for accessing agriculture information. Study further revealed th...
