Insulator to Metal Transition in WO Induced by Electrolyte Gating
X. Leng, J. Pereiro, J. Strle +8
Tungsten oxide and its associated bronzes (compounds of tungsten oxide and an alkali metal) are well known for their interesting optical and electrical characteristics. We have mod…
In-plane and transverse superconducting fluctuation diamagnetism in the presence of charge-density waves in 2H-NbSe2 single crystals
F. Soto, H. Berger, L. Cabo +4
The fluctuation-diamagnetism (FD) above the superconducting transition was measured in 2H-NbSe2 single crystals. The moderate uniaxial anisotropy of this compound, and some experim…
Electric and magnetic characterization of NbSe2 single crystals: anisotropic superconducting fluctuations above Tc
F. Soto, H. Berger, L. Cabo +5
Electric and magnetic characterization of NbSe2 single crystals is first presented in detail. Then, some preliminary measurements of the fluctuation-diamagnetism (FD) above the tra…
Epitaxial growth and transport properties of Nb-doped SrTiO thin films
K. S. Takahashi, D. Jaccard, K. Shibuya +3
Nb-doped SrTiO epitaxial thin films have been prepared on (001) SrTiO substrates using pulsed laser deposition. A high substrate temperature () was fo…
Ruthenocuprates RuSr2(Eu,Ce)2Cu2O10: Intrinsic magnetic multilayers
I. Zivkovic, Y. Hirai, B. H. Frazer +8
We report ac susceptibility data on RuSr_2(Eu,Ce)_2Cu_2O_(10-y) (Ru-1222, Ce content x=0.5 and 1.0), RuSr_2GdCu_2O_8 (Ru-1212) and SrRuO_3. Both Ru-1222 (x=0.5, 1.0) sample types e…
