S.Le Floch, E.Gautier, P.Bordet, C.Acha, Y.Feng, A.Sulpice, J.L.Tholence, M.A.Alario Franco and M.Marezio, Physica C 266 (1996)
215. An increase of
more than 50 K is obtained in this compound, where the optimal doping is determined by high pressure experiments.
A STUDY OF THE TC PRESSURE DEPENDENCE IN THE HgBa2CuO4+d
SUPERCONDUCTOR USING THE EXTENDED HUBBARD HAMILTONIAN, E.V.L.
de Mello and C.Acha, Phys.Rev.B 56 (1997)
HIGH PRESSURE EFFECTS IN FLUORINATED HgBa2Ca2Cu3O8 , M. Monteverde, C. Acha, M. Núñez-Regueiro, D. A. Pavlov, K. A. Lokshin, S. N. Putilin and E. V. Antipov, Europhys. Lett. 72 (2005) 458. We obtain in this compound the record high superconducting Tc under pressure (166 K @ 23 GPa).
EVIDENCES OF A CONSOLUTE
CRITICAL POINT IN THE PHASE SEPARATION REGIME OF La5/8-
yPryCa3/8MnO3 (y=0.4) SINGLE CRYSTALS, G. Garbarino,
C. Acha, P. Levy, T. Y. Koo
and S-W. Cheong
Phys. Rev. B
74 (2006) 100401(R). A
particular critical behavior
of the breakdown
field is observed in this phase-separated compound that points
to the existence
of a consolute point .
TOMONAGA-LUTTINGER
LIQUID AND COULOMB BLOCADE IN MULTIWALL CARBON NANOTUBES UNDER
PRESSURE, M. Monteverde, G. Garbarino,
M. Núñez-Regueiro, J. Souletie,
C. Acha, X. Jing, L. Lu, Z.
W. Pan, and S. S. Xie and R. Egger, Phys. Rev. Lett. 97 (2006) 176401. The syudy of the conductance of macroscopic multiwall nanotube (MWNT) bundles under pressure shows power laws
in temperature and voltage, as corresponding to a network of
bulk-bulk connected Tomonaga-Luttinger liquids (LLs)
MECHANISM FOR BIPOLAR RESISTIVE SWITCHING IN
TRANSITION-METAL OXIDES, M. J. Rozenberg, M. J. Sánchez, R. Weht, C. Acha, F. Gomez-Marlasca, and P.
Levy, Phys. Rev. B 81 (2010) 115101. With a simple model we explain non-trivial
characteristics of the resistive switching in complex oxide-metal interfaces.
