Field-tuned quantum effects in a triangular-lattice Ising magnet
We report thermodynamic and neutron scattering measurements of the triangular-lattice quantum Ising magnet TmMgGaO4 in longitudinal magnetic fields. Our experiments reveal a quasi-plateau state induced by quantum fluctuations. [...]

Extending MIEZE spectroscopy towards thermal wavelengths
A modulation of intensity with zero effort (MIEZE) setup is proposed for high-resolution neutron spectroscopy at momentum transfers up to 3 Å−1, energy transfers up to 20 meV and an energy resolution in the microelectronvolt range using both thermal and cold neutrons. MIEZE has two prominent advantages compared with classical neutron spin echo. [...]

Magnetic phase diagram of HoFeO$_3$ by neutron diffraction
Neutron diffraction studies of HoFeO$_3$ single crystals were performed under external magnetic fields. The interplay between the external magnetic fields, Dzyaloshinsky-Moria antisymmetric exchange, isotropic exchange interactions between Fe and Ho sublattices and within the Fe sublattice provides a rich magnetic phase diagram.

Inelastic neutron studies and diffraction in magnetic fields of TbFeO$_3$ and YbFeO$_3$
Investigations of the orthoferrites TbFeO$_3$ and YbFeO$_3$ were performed by neutron inelastic scattering and neutron single crystal diffraction in magnetic fields. The low temperature evolution of energy gaps was explored for both compounds and considered from the point of view of changes of rare earth ion anisotropy. [...]
