Electrical Resistivity and Thermal Expansion Measurements of URu2Si2 under Pressure
Gaku Motoyama, Nobuyuki Yokoyama, Akihiko Sumiyama +1
We carried out simultaneous measurements of electrical resistivity and thermal expansion of the heavy-fermion compound URu2Si2 under pressure using a single crystal. We observed a…
Specific Heat Study of Magnetic and Superconducting Transitions in CePt3Si
Gaku Motoyama, Katsuhiro Maeda, Yasukage Oda
Measurements of specific heat between 80 mK to 4 K and electrical resistivity between 80 mK to 10 K were carried out for polycrystalline CePt3Si samples cut into small pieces (typi…
AC/DC Susceptibility of the Heavy-Fermion Superconductor CePt3Si under Pressure
Yoshihiro Aoki, Akihiko Sumiyama, Gaku Motoyama +3
We have investigated the pressure dependence of ac and dc susceptibilities of the heavy-fermion superconductor CePt3Si (Tc= 0.75 K) that coexists with antiferromagnetism (TN = 2.2…
Stoner gap in the superconducting ferromagnet UGe2
N. Aso, G. Motoyama, Y. Uwatoko +7
We report the temperature () dependence of ferromagnetic Bragg peak intensities and dc magnetization of the superconducting ferromagnet UGe2 under pressure (). We have found…
NMR study of electronic state in CePt3Si
K. Ueda, K. Hamamoto, T. Kohara +2
In this article, we report the temperature dependence of spin-lattice relaxation rates at two Pt sites and one Si site in CePt3Si with a non-centrosymmetric structure center. 1/T1…
