Skutterudite Results Shed Light on Heavy Fermion Physics (2007)
Hassinger, E., Derr, J., Levallois, J., Aoki, D., Behnia, K., Bourdarot, F., ...
Only few selected examples among the great diversity of anomalous rare earth skutterudite are reviewed. Focus is first given on PrFe4P12 in comparison with URu2Si2. For PrFe4P12, great progress has...
de Haas-van Alphen oscillations in the underdoped cuprate YBa$_2$Cu$_3$O$_{6.5}$ (2007)
Jaudet, C., Vignolles, D., Audouard, A., Levallois, J., LeBoeuf, D., Doiron-Leyraud, N., ...
The de Haas-van Alphen effect was observed in the underdoped cuprate YBa$_2$Cu$_3$O$_{6.5}$ via a torque technique in pulsed magnetic fields up to 59 T. Above an irreversibility field of $\sim$30 T,...
Shubnikov-de Haas oscillations in YBa_2Cu_4O_8 (2007)
Bangura, A. F., Fletcher, J. D., Carrington, A., Levallois, J., Nardone, M., Vignolle, B., ...
We report the observation of Shubnikov-de Haas oscillations in the underdoped cuprate superconductor YBa$_2$Cu$_4$O$_8$ (Y124). For field aligned along the c-axis, the frequency of the oscillations...
