Research Abstract |
We have succeeded in growing a high quality single of ferromagnetUCu_2Si_2 and metamagnetic system UCoAl. In the case of UCu_2Si_2, we also succeeded inobserving the de Haas-van Alphen (dHvA) signal in the ferromagnetic state at low temperatures. From the measurements of angular dependence of dHvA signal, the electronic state of UCu_2Si_2 was revealed by comparison with the band calculation. We performed the magnetoresistivity measurements with fine tuning of the field direction on high quality single crystals of the ferromagnetic superconductor UCoGe. From these results, we found anomalous anisotropy of the upper critical field H_<c2>.
