Magnetic excitation in Sr2IrO4 : Establishing links to Cuprate superconductors
The strontium iridate Sr2IrO4 has recently received a special attention because of its closeresemblance to undoped high-Tc cuprate in terms of structural, electronic, and... -
Full reciprocal space imaging of the acoustic phonons in MgV2O4:
The proposal requests time to obtain a full mapping of the low-energy acoustic phonons. We have measured an acoustic phonon anomaly associated with the structural transition and... -
Paramagnetic excitations in BaFe2As2 at high temperature
One fundamental issue in the iron-based superconductors is whether the conventional local moment Heisenberg model is sufficient to describe magnetism in these materials, or... -
High-Energy dynamics and search for a continuum in CaFe2O4
We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it... -
Low-energy spin excitations in Ni over-doped NaFe0.7Ni0.3As
The discovery of iron-based superconductors gives a new horizon to study unconventional superconductivity. Typically iron-based superconductors can be created by doping (i.e.... -
High precision measurement of the spin waves in Yttrium Iron Garnet
Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications. It is a ferrimagnetic spinel with the narrowest ferromagnetic resonance linewidth of any known... -
Is there an incommensurate magnetic resonance in La2-xSrxCuO4?
Most optimally-doped high- Tc cuprate superconductors show a magnetic excitation (known as the 'resonance') at q=(pi,pi ) whose intensity increases sharply below Tc. This... -
RF-mSR study of high-Ge Si1-xGex alloys
Single crystal, bulk Si1-xGex alloys are available across the alloy composition range, and provide opportunity for study of alloy properties in transition between the two... -
Outer membrane mimics using novel thiol-PC
We have recently shown that dense monolayers of PC can be assembled on gold surfaces using a new omega thiol PC from Avanti. This has two advantages over our previous methods.... -
High energy spin excitation in superconducting Rb0.8Fe1.68Se2
Superconductivity (SC) in unconventional superconductors is believed to be related to magnetism. However, in AyFe1.6+xSe2 (A = K, Rb, Cs) system discovered in late 2010, the SC... -
Magnetic correlation length measurements in Fe/Si multilayers using spin echo...
We wish to investigate the magnetic structure of a series of magnetic multilayers using a new technique we have successfully implemented called Spin Echo Modulated Small Angle... -
The relationship between the pseudogap and magnetic excitations in La2-xSrxCuO4
This proposal is part of an ongoing project to relate the magnetic excitations to other electronic properties of the cuprate superconductors. We have recently proposed that the... -
Investigation on the air-water adsorption behaviour of N-acyl amino acid surf...
N-acyl amino acids are promising anionic amphiphilic molecules with an improved toxicological profile in comparison to the most common used sulfate-based surfactants. Previous... -
Investigation of Induced Magnetism at Graphene/EuO Interfaces
Interface effects are attracting a renewed interest in recent years. It resides in the fact that when an interface is formed the break of symmetry gives rise to entirely new... -
Polarized Neutron Reflectivity study of in-plane spin vortices formed in 2D r...
Spin vortices are most appealing characteristics of two dimensional 2D easy-plane spin systems which are receiving recent attention for their fundamental properties and possible... -
Structural Distortions in the Spin Ladder Compounds Ba2CuTe1-xWxO6
Ba2CuTeO6 has garnered considerable interest as the combination of stacking sequence and Cu2+ displacements lead to a magnetic geometry that reproduce the effects of a spin... -
Study of Quantum Anomalous Hall Effect Materials
We aim at studying materials that exhibit the Quantum Anomalous Hall Effect (QAHE) and understand the underlying mechanisms that provide the fine balance of ferromagnetic doping... -
Magnetic interactions in the room-temperature skyrmion material Co8Zn8Mn4
We propose an investigation of the spin-waves in the recently discovered room-temperature skyrmion material Co8Zn8Mn4. The ground state of Co8Zn8Mn4 is a very long wavelength... -
