The observation of ferromagnetism in CeCo3B2 with a high Curie temperature TC = 140 K and a magnetic moment 8 × 10−3 µB /F.U has been presented and explained by 4f itinerant magnetism with strong 4f-4f direct exchange interaction. The observed small magnetic moment can be understood by a cancellatio[r]

The aim of this study was to investigate the effects of high temperature on seed quality and peroxidase activity. High temperature stress was imposed on four brinjal genotypes at three levels (25 °C, 35 °C and 40 °C). Seeds were allowed to germinate on Petri-plates using two layers of filter paper i[r]
