Ac-magnetic susceptibility in the peak-effect region of NbSn
Olaf Bossen, Andreas Schilling, Naoki Toyota
We performed a systematic study of the ac magnetic-susceptibility on a Nb3Sn single crystal which displays a strong peak effect near the upper critical field Hc2. In external magne…
Anomalous infrared spectra of hybridized phonons in type-I clathrate BaGaGe
K. Iwamoto, S. Kushibiki, H. Honda +7
The optical conductivity spectra of the rattling phonons in the clathrate BaGaGe are investigated in detail by use of the terahertz time-domain spectroscopy. The…
Presence of a fluctuation related peak but absence of vortex-lattice melting in Nb3Sn in high resolution specific-heat measurements
M. Reibelt, N. Toyota
The melting of the magnetic vortex lattice has been observed in high-Tc superconductors in many experiments by different groups and is regarded as confirmed. To date, only one grou…
Current driven pinning strength in the vortex lattice of Nb3Sn aided by a small oscillating magnetic field
M. Reibelt, N. Toyota
By the application of a small oscillating magnetic field parallel to the main magnetic field and perpendicular to the transport current, we were able to generate a voltage dip in t…
Application of a small oscillating magnetic field to reveal the peak effect in the resistivity of Nb3Sn
Mark Reibelt, Andreas Schilling, Naoki Toyota
By the application of a small oscillating magnetic field parallel to the main magnetic field and perpendicular to the transport current, we were able to unveil the peak effect in t…
Optical conductivity from local anharmonic phonons
Hideki Matsumoto, Tatsuya Mori, Kei Iwamoto +3
Recently there has been paid much attention to phenomena caused by local anharmonic vibrations of the guest ions encapsulated in polyhedral cages of materials such as pyrochlore ox…
