概要
- 論文の詳細を見る
We succeeded in growing a high-quality single crystal of an antiferromagnet UPtGa_5 by the self-flux method, and measured the magnetic susceptibility, electrical resistivity, specific heat and de Haas-van Alphen (dHvA) oscillation. We found an antiferromagnetic transition at 26K from the magnetic susceptibility and electrical resistivity measurements. Six dHvA branches were observed, ranging from 1.14×10^7 to 1.13×10^8Oe. Fermi surfaces consist of two nearly cylindrical and two spherical Fermi surfaces. The cyclotron mass is large, ranging from 10 to 24m_0, which is consistent with the electronic specific heat coefficient γ=57mJ/K^2・mol.
