Nonmagnetic Phase Transition in LaTiSb Observed in Sb Nuclear Quadrupole Resonance
Masahiro Manago, Gaku Motoyama, Shijo Nishigori +2
We measured the electrical resistivity and the Sb nuclear quadrupole resonance (NQR) spectra of LaTiSb, which is a nonmagnetic reference system for a locally noncen…
Experimental determination of tantalum L-shell fluorescence yields and Coster-Kronig transition probabilities
Nils Wauschkuhn, Katja Frenzel, Burkhard Beckhoff +1
Using radiometrically calibrated instrumentation of Physikalisch-Technische Bundesanstalt, the L-shell fluorescence yields and Coster-Kronig factors of tantalum (including the unce…
Magnetoelectric Effect in the Antiferromagnetic Ordered State of CeTiBi with Ce Zig-Zag Chains
Masahiro Shinozaki, Gaku Motoyama, Masahiro Tsubouchi +8
In this study, we investigate the magnetoelectric (ME) effect of the newly discovered antiferromagnetic (AFM) compound CeTiBi with a hexagonal structure (space group $P…
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…
