Defect perturbation of the rotational states of NH4 in octahedral environments
The (NH4)0.02 Rbx K0.98-x I system offers advantages for the systematic study of tunnelling species and how they interact. Currently there are two models to explain the dynamics... -
Study of vibron quasibound state in RAg1-xCuxAl3, 0<x<1 (R=Ce and La) through...
We propouse the study of crystal-field or vibron excitations along the series RAgxCu1-xAl3 (R=Ce and La, 0<x<1), where we expect to studing two main aspects. The first one... -
Spin dynamics in the zig-zag ladder beta-CaCr2O4
We propose to investigate the spin dynamics in the frustrated antiferromagnet beta-CaCr2O4. Its structure consist in one dimensional chains of Cr+3 forming the legs of zig-zag... -
A µSR STUDY OF THE SUPERCONDUCTING GROUD STATE OF LA3NI2B2N3-d
The quaternary boronitride superconductor La3Ni2B2N3-d (Tc~12-14 K) has a layered structure where LaN-LaN-LaN triple layer blocks alternate with NiB layers. These NiB sheets are... -
Unstressed lattice parameter studies for weld residual stress determination
This study addresses the need to improve the reliability of measurements of weld residual stress; particularly for the type of welds used within the nuclear power industry. Such... -
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... -
Cation substitution in synthetic meridianiite (MgSO4.11D2O): phase behaviour ...
MgSO4.11H2O (MS11) is the most highly hydrated phase in the binary MgSO4¿H2O system. Whilst lower hydrates in this system have end-member analogues containing alternative... -
Probing perfume surface delivery / retention rates in-situ
This proposal is part of a funded (CASE) project, aimed at understanding the delivery of benefit actives (perfumes) to interfaces and the development of new self-assembled... -
MUSR studies in the spin ferromagnetic Nd0.75Gd0.25Rh3B2 and Nd0.8Tb0.2Al2 al...
We propose to characterize the two magnetic transitions in Nd0.75Gd0.25Rh3B2 and study the spin dynamics and field induced domain rotation via zero field (ZF) and longitudinal... -
Mineral phase determination in Mesopotamian seals and duck-weights: Objects f...
Mesopotamian seals and duckweights of the period 2000 - 1600 BC are often made of iron-stone which is usually refered to as 'heamatite'. In two prevoius experiments we have... -
MuSR study to investigation a small moment magnetic ordering in Ce(Os1-xFex)2...
Our recent musr studies on CeT 2Al10 (T=Os and Ru) reveal a clear sign of long range magnetic ordering below 28 K in both the compounds. More interestingly the frequency... -
Musr study of non-centrosymmetric heavy-fermion compounds: CeTSi3 (T=Pt and P...
In view of the interesting magnetic properties observed in CeTSi3 (T=Pt and Pd) and superconductivity in LaPdSi3 (TSC= 2.6 K), as well as the theoretical interest in... -
Amyloid β peptide and α-synuclein association at lipidmodel membranes
We plan to investigate the interaction between amyloid proteins and model biomembranes deposited on solid surfaces. The model membranes will be single zwitterionic and mixed... -
Investigation of giant crystal electric field (CEF) splitting in CeIr3Si2
CeIr3Si2 exhibits highly anisotropic bulk properties with two magnetic transitions at TN1 ~ 3.9 K and TN2 ~ 3.1 K. The overall CEF splitting of the J=5/2 ground multiplet of... -
Further crystal field excitation data for pyrochlore zirconates.
Nd2Zr2O7 (NZO), synthesized and supplied to us by Tokura and Onose, is a new candidate spin ice while Pr2Zr2O7 (PZO) if anything even more promising is supplied to us by... -
Neutron diffraction and inelastic neutron scattering study on NdT2Al10 (T= Ru...
We have investigated the magnetic structure and crystal field excitations (CEF) of CeT2Al10 (T=Os and Ru). The observed magnetic moment along the c-axis does not agree with that... -
The charge-ordered superstructure of YbFe2O4
There has been much recent interest in the so-called ¿novel¿ or ¿type-II¿ multiferroics, in which electrical polarisation appears at the onset of a particular type of magnetic... -
