Influence of Mg insert layers on interface magnetism in crystalline CoFe(B)/M...
We plan to continue our previous investigation on the influence of thin Mg insert layers on magnetism at buried interfaces in structures that model the lower electrode/barrier... -
Investigation of the low temperature magnetic order in azurite.
Both a natural mineral and quantum magnet, azurite is a candidate model of the so-called Distorted Diamond Chain system. Such a system should theoretically exhibit spin-1/3... -
Completing the magnetic ordering-crystal structure phase diagram of supercond...
We would like to complete the phase diagram by measuring one more sample of Fe1+xTe for x = 14 %, which represents a point at one extreme of the phase diagram. The simple binary... -
Magnetic excitations in CrB2
CrB2, like MnB2, are transition metal diborides that have magnetically ordered ground states. Preliminary neutron (TAS) work and in house lab indicated that the dispersion has... -
A combination study of the antiferromagnetism and diffusive magnetic scatteri...
As far as we know there is no single crystal neutron study on ErPr_2Si_2 yet, mainly due to fabrication difficulties. We have grown large (diameter: 6 mm; length: 8 mm) single... -
Investigation of the low temperature magnetic order in Cu nitrate
The aim of this proposal is to study the field induced magnetically ordered phase of the quasi 1D spin system copper nitrate. We plan to study the integrated intensities of the... -
High pressure evolution of magnetic state and crystal structure of Pr1-xCaxMn...
Recently insulator-metal transition in Pr0.7Ca0.3MnO3 was observed at P = 0.5 GPa, implying a change in magnetic ground state, which was initially a pseudo-CE AFM one. In later... -
Protein density profile near protein-resistant self-assembled monolayers: Sen...
Oligo(ethylene glycol) self-assembled monolayers (SAMs) effectively prevent the adsorption of proteins from biological media. Despite the importance of this effect for... -
Application of direct inversion to magnetic contrast datasets.
We have developed an experimental approach using a buried magnetic layer to provide contrast in systems consisting of complex biomolecular layers tethered to gold surfaces. This... -
Search for magnetic order in a frustrated triangular lattice organic system
This proposal is part of our research programme on novel quantum phases in frustrated lattices. Here we propose to determine the magnetic structure in a quasi-two-dimensional... -
YMnO3-x : Mn(I) in a mixed metal oxide ?
Topotactic reduction of YMnO3 with CaH2 yields three new reduced phases. Two of these phases appear to have compositions close to YMnO2.5 but with very different anion vacancy... -
Spin Dynamics in the Quantum Critical and Ferromagnetic Regimes of URu2-xRe
Recently, there has been a significant amount of interest in quantum phase transitions and non-Fermi liquid (NFL) behavior exhibited by heavy-fermion compounds. Interestingly... -

Coexistence of magnetic ordering and ferroelectricity in multiferroic materials, especially at high temperatures, is of great technological and fundamental interest. There are... -
Muon-spin rotation study of the in-plane magnetic penetration depth of REFe_(...
We propose a TF-muSR investigation of the superconducting properties of the REFe_(1-y)Ru_yAsO_{1-x}F_x compound (RE=La, Sm). In this system the substitution of Fe by the... -
Copy of: Pressure induced phase switching magnetic ordering in BiFeO3-PbTiO3
This experiment seeks to continue previous work on PEARL, whereby the phase is altered in the room temperature multiferroic BiFeO3 - PbTiO3 using hydrostatic pressure with the... -
Structure and magnetic properties of Sr4Fe6O12
Despite many previous attempts, Sr4Fe6O12 (the expected fully reduced composition for Sr4Fe6O13-x) has not been synthesised. It is of interest because it is believed to contain... -
Spin crossover and low temperature spin dynamics in In2VO5
The one dimensional material In2VO5 contains frustrated zigzag chains of corner sharing V 4+ (S = 1/2) square based pyramids interspersed with sheets of edge sharing InO6... -
Neutron scattering and muSR studies of magnetic phenomena in YFe2Al10: case s...
In strongly correlated electron systems, the proximity to magnetic ordering has been of special interest. Magnetism in this class of systems is often suppressed by the Kondo... -
