Manipulating exchange bias using all-optical helicity-dependent switching
Pierre Vallobra, Thibaud Fache, Yong Xu +5
Deterministic all-optical control of magnetization without an applied magnetic field has been reported for different materials such as ferrimagnetic and ferromagnetic thin films an…
Perpendicularly magnetized CoFeB multilayers with tunable interlayer exchange for synthetic ferrimagnets
Philipp Pirro, Abbass Hamadeh, Marion Lavanant-Jambert +7
A study of the multilayer system MgO/CoFeB(1.1nm)/Ta()/CoFeB(0.8nm)/MgO is presented, where the two CoFeB layers are separated by a Ta interlayer of varying thickness . The m…
Competing Structures in (In,Ga)Se and (In,Ga)2Se3 Semiconductors
J. Srour, A. Postnikov, M. Badawi +1
The electronic structure of four polytypes (beta, gamma, delta and epsilon) of hexagonal GaSe and InSe is calculated from first principles, using the WIEN2k and VASP codes and PBEs…
Near-forward Raman selection rules of the phonon-polariton created by alloying in (Zn,Be)Se
H. Dicko, O. Pages, F. Firszt +5
The Raman selection rules of the (ZnSe, BeSe) mixed phonon polariton created by alloying in the three mode (1ZnSe, 2BeSe) ZnBeSe system, whose dramatic S like dispersion covers the…
Pressure-induced phonon freezing in the ZnSeS II-VI mixed crystal: phonon-polaritons and ab initio calculations
R. Hajj Hussein, O. Pages, A. Polian +8
Near-forward Raman scattering combined with ab initio phonon and bond length calculations is used to study the phonon-polariton transverse optical modes (with mixed electrical and…
Two types of all-optical magnetization switching mechanisms using femtosecond laser pulses
M. S. El Hadri, P. Pirro, C. -H. Lambert +6
Magnetization manipulation in the absence of an external magnetic field is a topic of great interest, since many novel physical phenomena need to be understood and promising new ap…
Anisotropic thermal expansion of bismuth from first principles
B. Arnaud, S. Lebègue, G. Raffy
Some anisotropy in both mechanical and thermodynamical properties of bismuth is expected. A combination of density functional theory total energy calculations and density functiona…
Magnetic ground state and spin fluctuations in MnGe chiral magnet as studied by Muon Spin Rotation
N. Martin, M. Deutsch, F. Bert +9
We have studied by muon spin resonance (μSR) the helical ground state and fluctuating chiral phase recently observed in the MnGe chiral magnet. At low temperature, the muon polariz…
Propagation of acoustic waves in a von-Kármán vortex street like configuration of disclinations
Sébastien Fumeron, Bertrand Berche, Fernando Moraes +2
We show that a simple model of 1D array of topological defects in a crystalline environment is able to guide acoustic waves, depending on the angle of the incident wave. We comment…
Magnetovolume effect, macroscopic hysteresis and moment collapse in the paramagnetic state of cubic MnGe under pressure
N. Martin, I. Mirebeau, M. Deutsch +6
Itinerant magnets generally exhibit pressure induced transitions towards non magnetic states. Using synchrotron based X-ray diffraction and emission spectroscopy, the evolution of…
