Detecting an entanglement transition in a quantum magnet
Justification: We'd like to apply for three days Director’s Discretionary time on WISH to continue the experiment on measures of quantum entanglement in a model 1D magnet. This... -
Multiferroicity at high magnetic fields
CuFeO2 is a geometrically frustrated triangular lattice system. At low temperatures it shows a number of different spin orders with applied magnetic field. CuFeO2 also has a... -
Investigation of Bose-Einstein condensation of magnons through temperature-fi...
YbAl3C3 exhibits a spin gap formation due to spin dimer ground state below 10 K. In zero-field the ground state is paramagnetic and no sign of long range magnetic ordering down... -
Magnetic phase diagram of multiferroic GdMn2O5
In the last five years, we have carried out a comprehensive study of the family of REMn2O5 multiferroics by neutron and X-ray magnetic scattering, providing details about the... -
Anomalously slow magnetic relaxation in a multi-q helimagnetic phase of SrFeO3
Non-coplanar magnetic orders in metallic helimagnets have been of great interest since the discovery of a vortex-like spin-swirling object called "skyrmion" and the resulting... -
High magnetic field phase of magnetoelectric Cr2O3
Multiferroics have been highly topical in the past decade due to potential applications in, amongst others, data storage. Cr2O3 was the first linear magnetoelectric compound,... -
Investigation of bilinear magnetoelectric effect in magnetic field-induced mu...
We propose to perform a neutron diffraction experiment under magnetic fields using a single crystal sample of multiferroic alpha-NaFeO2 on WISH beamline. Recently, we have... -
Electric field effects on the spin correlation length in multiferroic delafos...
In a previous WISH experiment, we have succeeded in determining the incommensurate cycloidal magnetic structure of AgFeO2, which induces a ferroelectric polarization[1].... -
In-situ hydrogen decomposition studies of ammonia borane and the diammoniate ...
Ammonia borane (AB) is one of the most promising hydrogen storage materials. We have extensively studied the low temperature behaviour of this material This proposal asks for 3... -
Investigation of Jahn-Teller assisted polaron collapse beyond the percolation...
Polaron-mediated colossal magneto-resistance (CMR) was predicted decades ago but never been experimentally established unambigously, despite the 'universal' existence of... -
On the inhomogeneous ground state of the two-dimensional frustrated antiferro...
The layered NaMnO2 is challenging as it is an experimental realization of a two-dimensional spin-2, spatially anisotropic triangular lattice, where the interplay of temperature...
