Thermodynamic study of gap structure and pair-breaking effect by magnetic field in the heavy-fermion superconductor CeCu2Si2
Shunichiro Kittaka, Yuya Aoki, Yasuyuki Shimura +7
This paper presents the results of specific-heat and magnetization measurements, in particular their field-orientation dependence, on the first discovered heavy-fermion superconduc…
Thermodynamic Study of Nodal Structure and Multiband Superconductivity of KFe2As2
Shunichiro Kittaka, Yuya Aoki, Naoki Kase +12
The temperature, field, and field-orientation dependences of the electronic specific heat Ce of the ironpnictide superconductor KFe2As2 have been investigated. Thermodynamic eviden…
Multiband superconductivity with unexpected deficiency of nodal quasiparticles in CeCu2Si2
Shunichiro Kittaka, Yuya Aoki, Yasuyuki Shimura +6
Superconductivity in the heavy-fermion compound CeCu2Si2 is a prototypical example of Cooper pairs formed by strongly correlated electrons. For more than 30 years, it has been beli…
Superconducting gap structure of CeIrIn5 from field-angle-resolved measurements of its specific heat
Shunichiro Kittaka, Yuya Aoki, Toshiro Sakakibara +5
In order to identify the gap structure of CeIrIn5, we measured field-angle-resolved specific heat C(phi) by conically rotating the magnetic field H around the c axis at low tempera…
Spin Fluid Dynamics Observed by Magnetic Fountain Effect and Mechano-Spin Effect in the Ferromagnetic Superfluid He A Phase
Y. Aoki, A. Yamaguchi, K. Suzuki +2
Systematic observations of the magnetically generated fountain pressure in the superfluid He A have been carried out in a newly built apparatus designed to reduce the effec…
