Non-volatile resistive switching in dielectric superconductor YBCO
C. Acha, M. J. Rozenberg
We report on the reversible, nonvolatile and polarity dependent resistive switching between superconductor and insulator states at the interfaces of a Au/YBaCuO (YB…
Pressure effects in the triangular layered cobaltites NaxCoO2
G. Garbarino, M. Monteverde, M. Nunez Regueiro +3
We have measured transport properties as a function of temperature and pressure up to 30GPa in the NaxCoO2 system. For the x=0.5 sample the transition temperature at 53K increases…
Evidences of a consolute critical point in the Phase Separation regime of La(5/8-y)Pr(y)Ca(3/8)MnO(3) (y = 0.4) single crystals
G. Garbarino, C. Acha, P. Levy +2
We report on DC and pulsed electric field sensitivity of the resistance of mixed valent Mn oxide based La(5/8-y)Pr(y)Ca(3/8)MnO(3) (y = 0.4) single crystals as a function of temper…
Electrical resistivity of the Ti4O7 Magneli phase under high pressure
C. Acha, M. Monteverde, M. Nunez-Regueiro +2
We have measured resistivity as a function of temperature and pressure of Ti4O7 twinned crystals using different contact configurations. Pressures over 4kbar depress the localizati…
Revealing polarons with high pressure on low electron-doped manganites
G. Garbarino, C. Acha, D. Vega +5
Pressure sensitivity (up to 1 GPa) of the electrical resistivity and of the ac susceptibility was measured for low electron doping levels of CaYMnO (CYMO) and of Ca…
