Ferromagnetism and Lattice Distortions in the Perovskite YTiO
W. Knafo, C. Meingast, H. v. Löhneysen +7
The thermodynamic properties of the ferromagnetic perovskite YTiO are investigated by thermal expansion, magnetostriction, specific heat, and magnetization measurements. The lo…
The BMV project: Search for photon oscillations into massive particles
C. Robilliard, B. Pinto Da Souza, F. Bielsa +6
In this contribution to PSAS08 we report on the research activities developed in our Toulouse group, in the framework of the BMV project, concerning the search for photon oscillati…
Multiple Quantum Oscillations in the de Haas van Alphen Spectra of the Underdoped High Temperature Superconductor YBa_2Cu_3O_6.5
Alain Audouard, Cyril Jaudet, David Vignolles +5
By improving the experimental conditions and extensive data accumulation, we have achieved very high-precision in the measurements of the de Haas-van Alphen effect in the underdope…
Magneto-transmission of multi-layer epitaxial graphene and bulk graphite: A comparison
M. Orlita, C. Faugeras, G. Martinez +6
Magneto-transmission of a thin layer of bulk graphite is compared with spectra taken on multilayer epitaxial graphene prepared by thermal decomposition of a SiC crystal. We focus o…
Alignment Dynamics of Single-Walled Carbon Nanotubes in Pulsed Ultrahigh Magnetic Fields
J. Shaver, A. N. G. Parra-Vasquez, S. Hansel +6
We have measured the dynamic alignment properties of single-walled carbon nanotube (SWNT) suspensions in pulsed high magnetic fields through linear dichroism spectroscopy. Millisec…
Approaching the Dirac point in high mobility multi-layer epitaxial graphene
Milan Orlita, Clement Faugeras, Paulina Plochocka +8
Multi-layer epitaxial graphene (MEG) is investigated using far infrared (FIR) transmission experiments in the different limits of low magnetic fields and high temperatures. The cyc…
Effect of magnesium doping on the orbital and magnetic order in LiNiO2
M. Bonda, M. Hopzapfel, Sophie De Brion +6
In LiNiO2, the Ni3+ ions, with S=1/2 and twofold orbital degeneracy, are arranged on a trian- gular lattice. Using muon spin relaxation (MuSR) and electron spin resonance (ESR), we…
Critical Scaling of the Magnetization and Magnetostriction in the Weak Itinerant Ferromagnet UIr
W. Knafo, C. Meingast, S. Sakarya +5
The weak itinerant ferromagnet UIr is studied by magnetization and magnetostriction measurements. Critical behavior, which surprisingly extends up to several Tesla, is observed at…
Effect of grain refinement on enhancing critical current density and upper critical field in undoped MgB2 ex-situ tapes
A. Malagoli, V. Braccini, M. Tropeano +9
Ex-situ Powder-In-Tube MgB2 tapes prepared with ball-milled, undoped powders showed a strong enhancement of the irreversibility field H*, the upper critical field Hc2 and the criti…
Field Dependence of the Ground State in the Exotic Superconductor CeCoIn: a Nuclear Magnetic Resonance Investigation
G. Koutroulakis, V. F. Mitrović, M. Horvatić +3
We report In nuclear magnetic resonance (NMR) measurements in CeCoIn at low temperature ( mK) as a function of magnetic field () from 2 T to 13.5 T a…
Comment on ``Texture in the Superconducting Order Parameter of CeCoIn Revealed by Nuclear Magnetic Resonance''
V. F. Mitrović, G. Koutroulakis, M. Klanjšek +4
The study of the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state has been of considerable recent interest. Below the temperature which is believed to be the transition temperat…
Similar glassy features in the NMR response of pure and disordered La1.88Sr0.12CuO4
V. F. Mitrovic, M. -H. Julien, C. de Vaulx +4
High Tc superconductivity in La2-xSrxCuO4 coexists with (striped and glassy) magnetic order. Here, we report NMR measurements of the 139La spin-lattice relaxation, which displays a…
Magneto-transmission as a probe of Dirac fermions in bulk graphite
M. Orlita, C. Faugeras, G. Martinez +4
Far infrared magneto-transmission spectroscopy has been used to probe "relativistic" fermions in highly oriented pyrolytic and natural graphite. Nearly identical transmission spect…
Boundary-mediated electron-electron interactions in quantum point contacts
Vincent Thomas Francois Renard, O. A. Tkachenko, V. A. Tkachenko +4
An unusual increase of the conductance with temperature is observed in clean quantum point contacts for conductances larger than 2e^2/h. At the same time a positive magnetoresistan…
