Half-integer Shapiro steps at the 0-pi crossover of a ferromagnetic Josephson junction
H. Sellier, C. Baraduc, F. Lefloch +1
We investigate the current-phase relation of S/F/S junctions near the crossover between the 0 and the pi ground states. We use Nb/CuNi/Nb junctions where this crossover is driven b…
Investigation of thermal and magnetic properties of defects in a spin-gap compound NaV2O5
A. I. Smirnov, S. S. Sosin, R. Calemczuk +4
The specific heat, magnetic susceptibility and ESR signals of a Na-deficient vanadate Na_xV_2O_5 (x=1.00 - 0.90) were studied in the temperature range 0.07 - 10 K, well below the t…
Andreev Reflection Enhanced Shot Noise in Mesoscopic SNS Junctions
X. Jehl, P. Payet-Burin, C. Baraduc +2
Current noise is measured with a SQUID in low impedance and transparent Nb-Al-Nb j unctions of length comparable to the phase breaking length and much longer than the thermal lengt…
SQUID based resistance bridge for shot noise measurement on low impedance samples
X. Jehl, P. Payet-Burin, C. Baraduc +2
We present a resistance bridge which uses a SQUID to measure the shot noise in low impedance samples. The experimental requirements are high DC bias currents (typically 10mA) toget…
Thermodynamic Properties of the Spin-1/2 Antiferromagnetic ladder Cu2(C2H12N2)2Cl4 under Magnetic Field
R. Calemczuk, J. Riera, D. Poilblanc +4
Specific heat () measurements in the spin-1/2 Cu(CHN)Cl system under a magnetic field up to are reported and compared to the results of n…
