Cross-relaxation and phonon bottleneck effects on magnetization dynamics in LiYF4:Ho3+
S. Bertaina, B. Barbara, R. Giraud +5
Frequency and dc magnetic field dependences of dynamic susceptibility in diluted paramagnets LiYF:Ho have been measured at liquid helium temperatures in the ac and dc ma…
How many bits may fit in a single magnetic dot? XMCD-PEEM evidences the switching of Néel caps inside Bloch domain walls
Fabien Cheynis, Aurélien Masseboeuf, Olivier Fruchart +5
Data storage relies on the handling of two states, called bits. The market of mass storage is currently still dominated by magnetic technology, hard disk drives for the broad publi…
Near-field optical microscopy with a nanodiamond-based single photon tip
A. Cuche, A. Drezet, Y. Sonnefraud +4
We introduce a point-like scanning single-photon source that operates at room temperature and offers an exceptional photostability (no blinking, no bleaching). This is obtained by…
High-field recovery of the undistorted triangular lattice in the frustrated metamagnet CuFeO2
T. T. A. Lummen, C. Strohm, H. Rakoto +2
Pulsed field magnetization experiments extend the typical metamagnetic staircase of CuFeO2 up to 58 T to reveal an additional first order phase transition at high field for both th…
Chemically-induced Mobility Gaps in Graphene Nanoribbons: A Route for Upscaling Device Performances
Blanca Biel, François Triozon, X. Blase +1
We report a first-principles based study of mesoscopic quantum transport in chemically doped graphene nanoribbons with a width up to 10 nm. The occurrence of quasibound states rela…
Interplay of inequivalent atomic positions in resonant x-ray diffraction of Fe3BO6
G Beutier, E Ovchinnikova, S P Collins +8
'Forbidden' Bragg reflections of iron orthoborate Fe3BO6 were studied theoretically and experimentally in the vicinity of the iron K edge. Their energy spectra are explained as res…
