Magnetic field induced enlargement of the regime of critical fluctuations in the classical superconductor V3Si from high-resolution specific heat experiments

Y. Zheng, Y. Liu, N. Toyota +1

We report high-resolution specific heat data on a high-quality single crystal of the classical superconductor V3Si, which reveal tiny lambda-shape anomalies appearing superimposed…

Optical conductivity spectra of the rattling phonons and charge carriers in type-VIII clathrate Ba $_{8}$ Ga $_{16}$ Sn $_{30}$

K. Iwamoto, T. Mori, S. Kajitani +6

We have investigated optical conductivity spectra of $n$ - and $p$ -type Ba $_{8}$ Ga $_{16}$ Sn $_{30}$ ( $α$ -BGS) with type-VIII clathrate structure, at temperatures from 296\,K down to 6…

Optical conductivity of rattling phonons in type-I clathrate Ba $_{8}$ Ga $_{16}$ Ge $_{30}$

T. Mori, S. Goshima, K. Iwamoto +9

A series of infrared-active optical phonons have been detected in type-I clathrate Ba $_{8}$ Ga $_{16}$ Ge $_{30}$ by terahertz time-domain spectroscopy. The conductivity spectra with the…

Thermal fluctuations and vortex melting in the classical superconductor Nb3Sn from high-resolution specific-heat measurements

R. Lortz, F. Lin, N. Musolino +4

The range of critical thermal fluctuations in classical bulk superconductors is extremely small and especially in low fields hardly experimentally inaccessible. With a new type of…
