INS study of the exchange couplings and magnetic anisotropies in Ni(II), Mn(I...
SQUID magnetometry is the first and most trivial step when studying magnetic systems. However reliable conclusions can only be made in cases of very simple systems. When the... -
Spin-phonon coupling in heavy fermion CeAuAl3 and CeCuAl3 compounds
To understand this novel ground state of CeCuAl3, we have carried out low and high-energies inelastic neutron scattering (INS) measurements using the IRIS and HET spectrometers.... -
What is the cause for the gapped mode in the `BEC' phase of DTN?
Arguably the most-famous quantum phase transition is the Bose-Einstein condensation (BEC) of magnons. It can be studied experimentally in gapped quantum paramagnets when an... -
Superconductivity and critical spin fluctuations
In a successful recent experiment on IN5 (ILL), we have been able to show that in contrast to commonly accepted wisdom, the excitation gap in nearly optimally doped... -

We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is... -
Tuning confinement potential of spinons in an Ising chain using magnetic fields
The Ising chain realises the fundamental paradigm of spin fractionalization, where locally flipping a spin creates two kinks (spinons) that can separate away at no energy cost,... -
Spin excitations in the pseudogap region of YBCO6.5 Ortho-II Superconductor
We propose to investigate the spin dynamics in the Ortho-II order YBCO6.5 superconductor at energies above 100 meV. This study will be aimed at searching for the broadening of... -

We are proposing to characterize the short range magnetic correlations and dynamics in a single crystal of Yb3Ga5O12, a geometrically frustrated spin liquid candidate. We have... -
Magnon-phonon coupling in magnetoelectric HoMnO3
The manipulation of magnetic properties electronically is of great importance in modern computing. Current technology uses electric currents which draws a relatively large... -
Inelastic magnetic scattering in CePd3
CePd3 is a classic intermediate valence (IV) system. In MAPS experiment 620167 we obtained an important qualitative result for CePd3, namely that the Kondo-like scattering... -
Muon Spin Relaxation detection of Spin-Polarized Conduction Electrons in Silicon
The proposed experiment is to observe optical spin-injection in Silicon through MuSR detection. An important part of research in next generation electronics focusses on the... -

Ethanol plays an important role in the human metabolism. It is in particular known to act as a drug enhancer by increasing trans-membrane permeability, and as an anesthetic.... -
Inelastic neutron scattering study of the metallic toroidal system UNi4B
There is considerable interest in understanding the magnetoelectric effect with the aim of developing technological applications. Until recently this has been limited to... -
Quantum critical dynamics in the purely dipolar antiferromagnet LiErF4
LiErF4 is an example of an XY dipolar coupled antiferromagnet with planar anisotropy. As such it exhibits a quantum phase transition (QPT) in a small field of 4kOe, which is of... -
Neutron scattering study of a triangular-lattice NaYbO2: a quantum spin liqui...
The Quantum spin liquid (QSL) state continues to fascinate the condensed matter community. This is because the spins in a QSL are highly entangled and fluctuate strongly down to... -
Spin excitations in CeCoSi under hydrostatic pressure
The meta-orbital transition is a new theoretical concept to explain the nature of quantum criticality in heavy-fermion systems. Such a transition can occur e.g. as function of...
