Sinusoidal electromagnon in RMnO3: Indication of anomalous magnetoelectric coupling [PDF]

, 2011
The optical spectra in the family of multiferroic manganites RMnO3 is a great puzzle. Current models can not explain the fact that two strong electromagnons are present in the non-collinear spin cycloidal phase, with only one electromagnon surviving the ...

Dynamics of solar wind protons reflected by the Moon [PDF]

, 2010
Solar system bodies that lack a significant atmosphere and significant internal magnetic fields, such as the Moon and asteroids, have been considered as passive absorbers of the solar wind. However, ion observations near the Moon by the SELENE spacecraft

USING THE 3D MODEL IN THE MANUFACTURING AND CONTROL PROCESS OF THE CYCLOID PROFILE WHEELS

Journal of Industrial Design and Engineering Graphics, 2006
In the vibroacoustic performances of the cycloid gear reducer, major influences have the technological parameters: the shape errors of the wells’ tooth and the roughness of the active cycloid profile.

Ginzburg-Landau theory for the conical cycloid state in multiferroics: applications to CoCr$_2$O$_4$

, 2008
We show that the cycloidal magnetic order of a multiferroic can arise in the absence of spin and lattice anisotropies, for e.g., in a cubic material, and this explains the occurrence of such a state in CoCr$_2$O$_4$.

Temperature-dependent properties of the magnetic order in single-crystal BiFeO3

, 2011
We report neutron diffraction and magnetization studies of the magnetic order in multiferroic BiFeO3. In ferroelectric monodomain single crystals, there are three magnetic cycloidal domains with propagation vectors equivalent by crystallographic symmetry.

Interpolation on cycloidal spaces

Journal of Approximation Theory, 2014
In this contribution the authors deal with Hermite interpolation problems on cycloidal spaces. Let us remind that a cycloidal space \(C_{n}\) of dimension \(n+1\) is the linear space generated by \(\{\cos x,\sin x, 1,x,\dots, x^{n-2}\},\) \(n\geq 2,\) and \(C_{1}= \operatorname{span}\{\cos x, \sin x\}\).
