Magnetic fluctuations in the presence of charge order RbFe2+Fe3+F6
We propose to investigate the magnetic fluctuations in a charge ordered magnet. Rb(Fe2+Fe3+)F6 is loosely based on a distorted Kagome framework with alternating chains of... -
Study of hybridization gap formation in a single crystal of the heavy-Fermion...
The solution of the Anderson lattice model (ALM) leads to two renormalized bands near EF with an energy gap due to hybridization between the 4f- and conduction electrons. The... -
1D Spin-1/2 Chain Dispersion of Magnetoelectric CuO
We propose to measure the high energy magnetic dispersion of CuO. At high energies, CuO exhibits quasi-1D spin-1/2 chain magnetic behaviour. Our previous studies have revealed... -
Electronic state of Co3+ in LaCoO3
We will search for spin-orbit transitions of the Co3+ ions in LaCoO3. The ground state is a non-magnetic singlet, but there continues to be a debate about the nature of the... -
INS investigation of post-pressurised Cs2CuCl4
Cs2CuCl4 has been extensively studied using neutron scattering, and has revealed a quantum spin liquid phase below 2.8 K with antiferromagnetic interactions, and long range... -
Spin excitations in overdoped BaFe1.82Ni0.18As2
The relationship between spin fluctuations and superconductivity is an important issue in condensed matter physics. Part of evidence suggesting direct correlation between spin... -
Magnetic excitations in single-crystals of LaFeAsO
We aim to determine the magnetic excitation spectrum in single-crystals of the parent LaFeAsO compound and thereby address some basic issues concerning the nature of the... -
Spin dynamics in FeSi
At low temperatures FeSi is a non-magnetic insulator, but becomes a metallic paramagnet for T > 300K. It has been proposed to be a Kondo insulator in which local electron... -

A recently discovered new class of geometrically frustrated magnets is the family of cobalt oxides RBaCo4O7 (R=rare earth or Y). The structure is built up CoO4 tetrahedra which... -
Spin dynamics of the Mn12 prototype nanomagnet fully unravelled by 4-dimensio...
Mn12, with an anisotropy barrier close to 65 K, has been for 20 years a prototype nanomagnet, but in spite of a number of investigations the actual link between the value of the... -
Magnetic excitations of the model one-dimensional metal K0.3MnO3
Understanding the electronic properties of low-dimensional systems remains one of the central challenges of condensed matter physics. Although great progress has been made in... -
Fractionalized Spin Excitation in Ce2Zr2O7 Pyrochlore
In recent years, there has been a great interest in quantum spin liquid (QSL). The QSL state is characterized by no conventional order parameter associated with a broken... -

Role of interstitial oxygen ordering on the spin excitation of Pr2-xSrxNiO4+d
Dynamics of charge and spin stripe in 214-type nickelets (La2-xSrxNiO4+d) have been investigated intensively in last two decades as similar electronic ordering was found in... -
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... -
