Polarized Neutron Diffraction in the Single-Crystal Studies

Autor: I. A. Zobkalo

Publikováno v: Crystallography Reports. 66:216-230

A review of various methods based on the use of polarized neutron diffraction with and without subsequent polarization analysis is presented. Various methods of polarized neutron diffraction for studying magnetic properties of materials have been the

Autor: Björn Pedersen, S. V. Shiryaev, Andrew Sazonov, S. N. Barilo, I. A. Zobkalo, A. N. Matveeva, Vladimir Hutanu

Publikováno v: Physical Review B. 101

Detailed investigation of the incommensurate magnetic ordering in a single crystal of multiferroic $\mathrm{NdM}{\mathrm{n}}_{2}{\mathrm{O}}_{5}$ has been performed using both nonpolarized and polarized neutron-diffraction techniques. Below ${T}_{N}\

Probing the role of Nd3+ ions in the weak multiferroic character of NdMn2O5 by optical spectroscopies

Autor: Patrick Fournier, S. Jandl, S. V. Shiryaev, S. Mansouri, S. N. Barilo, Milan Orlita, Mohamed Balli, B. Roberge, I. A. Zobkalo

Publikováno v: Physical Review B. 98

Raman and infrared spectroscopies are used as local probes to study the dynamics of the Nd-O bonds in the weakly multiferroic ${\mathrm{NdMn}}_{2}{\mathrm{O}}_{5}$ system. The temperature dependence of selected Raman excitations reveals the splitting

Temperature hysteresis of magnetic phase transitions in Tb1 − x Ce x Mn2O5 (x = 0, 0.20, 0.25)

Autor: S. V. Gavrilov, E. I. Golovenchits, I. A. Zobkalo, V. A. Sanina

Publikováno v: Physics of the Solid State. 56:51-56

The temperature evolution of the magnetic structure of multiferroics Tb1 − xCexMn2O5 (x = 0, 0.20, 0.25) has been investigated using the neutron scattering methods. It has been found that, despite the qualitative similarity of the magnetic states a
