Puzzling evidence for surface superconductivity in the layered dichalcogenide CuTiSe

F. Levy-Bertrand, B. Michon, J. Marcus +4

We report on specific heat and magnetotransport measurements performed on superconducting CuTiSe single crystals. We show that superconductivity persists in transport…

Excitonic resonances in thin films of WSe2: From monolayer to bulk material

Ashish Arora, Maciej Koperski, Karol Nogajewski +3

We present optical spectroscopy (photoluminescence and reflectance) studies of thin layers of the transition metal dichalcogenide WSe2, with thickness ranging from mono- to tetra-l…

Experimental consequences at high temperatures of quantum critical points

D. C. Freitas, P. Rodière, M. Núñez +4

We study the Cr_(1-x) Re_x phase diagram finding that its phase transition temperature towards an antiferromagnetic order T_N follows a quantum [(x_c-x)/x_c ]^ψ law, with ψ=1/2, fr…

Multiplicative noise and charge density wave dynamics in Rb0.30MoO3

J. Dumas, J. Marcus

We have investigated the combined effects of a multiplicative noise and nonlinear conductivity on the charge density wave (CDW) dynamics of the quasi-one dimensional conductor Rb0.…

Broad band noise and stochastic resonance in the CDW conductors K0.30MoO3 and K0.30Mo(1-x)WxO3 (x=0.001 and x=0.002)

J. Dumas, J. Marcus

We have investigated nonlinear characteristics and broad band noise in the quasi-one dimensional charge-density-wave conductors K0.30MoO3 and K0.30Mo(1-x)WxO3 (x=0.001 and x=0.002)…

Dependence of the structural and physical properties of Tl1-yFe2-z(Se1-xSx)2 with isovalent substitution of Se by S: decrease of TNeel with S content

P. Toulemonde, D. Santos-Cottin, Ch. Lepoittevin +2

The effect of selenium substitution by sulfur or tellurium in the Tl1-yFe2-zSe2 antiferromagnet was studied by x-ray and electron diffraction, magnetization and transport measureme…
