High Electron Mobility in Epitaxial Graphene on 4H-SiC(0001) via post-growth annealing under hydrogen
E. Pallecchi, F. Lafont, V. Cavaliere +4
We investigate the magneto-transport properties of epitaxial graphene single-layer on 4H-SiC(0001), grown by atmospheric pressure graphitization in Ar, followed by H2 intercalation…
Resonant photon absorption in the low spin molecule V15
W. Wernsdorfer, A. Mueller, D. Mailly +1
We report the first study of the micro-SQUID response of a molecular system to electromagnetic radiation. The advantages of our micro-SQUID technique in respect to pulsed electron…
Tunneling of magnetization versus spin-phonon and spin-spin transitions in LiY_0.998Ho_0.002F_4
R. Giraud, W. Wernsdorfer, A. M. Tkachuk +2
Strong hyperfine coupling in a 0.2% Holmium doped LiYF_4 single crystal induces staircaselike hysteresis loops of the magnetization at very low temperatures. The field sweep rate d…
Magnetization reversal by uniform rotation (Stoner-Wohlfarth model) in f.c.c. cobalt nanoparticles
W. Wernsdorfer, C. Thirion, N. Demoncy +2
The combination of high sensitive superconducting quantum interference device (SQUID) with high quality nanoparticles allowed to check the simplest classical model describing the m…
Observation of the distribution of molecular spin states by resonant quantum tunneling of the magnetization
W. Wernsdorfer, T. Ohm, C. Sangregorio +3
Below 360 mK, Fe magnetic molecular clusters are in the pure quantum relaxation regime and we show that the predicted square-root time relaxation is obeyed, allowing us to develop…
