Helimagnetism of Fe: High pressure study of an Y2Fe17 single crystal
Combined neutron diffraction and magnetization measurements under pressure showed that the collinear ferromagnetic phase of Y2Fe17 is substituted by the pressure induced helical incommensurate phases. The complex pressure-temperature-field behavior o...

Pressure induced helimagnetism in Fe-based (Y2Fe17, Lu2Fe17) intermetallic compounds
The helimagnetic ground state was induced in the hexagonal Y2Fe17 and Lu2Fe17 intermetallics by hydrostatic pressure above 1.05 and 0.3 GPa, respectively. The observed incommensurate helical structure was characterized by a propagat...

Magnetization and neutron diffraction studies of Lu2Fe17 under high pressure
Combined magnetization and neutral diffraction measurements under high hydrostatic pressure up to 1 GPa were performed to study magnetic structures and their evolution in an Lu2Fe17 single crystal. Mechanisms of the helimagnetic-fer...

Helimagnetic order in the re-entrant ferromagnet Ce2 Fe15.3 Mn1.7./sub
Magnetic structures and magnetic interactions in the re-enrant ferromagnetic Ce2 Fe15.3 Mn1.7 compound have been studied using both microscopic and macroscopic measurements under high pressures up to 8 kbar. The preferential placement of Mn ...

Comment on "Competition between helimagnetism and commensurate quantum spin correlations in LiCu2O2
It is shown that the theoretical model proposed in the reference Phys. Rev. Lett, 92, (2004), 177201 is not in consistency with experimental data for neutron scattering in LiCu2O2......

Effect of uniaxial pressure on helimagnetic structure in Lu2Fe17.
The incommensurate helimagnetic structure (IHS) in the Lu2Fe17 intermetallics has been induced at 5 K by hydrostatic pressure above 0.3 GPa and characterized by a propagation vector (00tz). The observed dependence of tz on external ...

Chiral criticality in helimagnet Ho studied by polarized neutron scattering.
The critical exponents for the average chirality, beta(d) = 0.90(3), and the chiral susceptibility, gamma(c) = 0.68(6), are determined for the spin-ordering transition in helimagnet Ho. The beta(c) is extraordinarily large and twice higher t...
