Local tetragonal distortion in La_{0.7}Sr_{0.3}MnO_3 strained thin films probed by x-ray absorption spectroscopy
Narcizo M. Souza-Neto, Aline Y. Ramos, Hélio C. N. Tolentino +2
We report on an angular resolved X-ray Absorption Spectroscopy study of thin films epitaxially grown by pulsed laser deposition on slightly mismatched sub…
Comment on 'Quantum Coherence between High Spin Superposition States of Single Molecule Magnet Ni4'
W. Wernsdorfer
In a recent paper, cond-mat/0405331 (Ref. 1), del Barco et al. reported experimental studies on a Ni4 molecular system. They used an experimental method (combining microwave spectr…
Comment on 'Pulsed field studies of the magnetization reversal in molecular nanomagnets'
W. Wernsdorfer, N. E. Chakov, G. Christou
In a recent paper, cond-mat/0404041, J. Vanacken et al. reported experimental studies of crystals of Mn12-ac molecular nanomagnets in pulsed magnetic fields with sweep rates up to…
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…
Valence bond crystal in a pyrochlore antiferromagnet with orbital degeneracy
S. Di Matteo, G. Jackeli, C. Lacroix +1
We discuss the ground state of a pyrochlore lattice of threefold-orbitally-degenerate magnetic ions. We derive an effective spin-orbital Hamiltonian and show that the orbit…
