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... -
Inelastic neutron scattering investigations of the high temperature phase tra...
Recently it has been reported that YbAl3C3 undergoes an antiferromagnetic quadrupolar ordering transition at 80 K, Further study by Ochiai et al. revealed that the transition at... -
Spin excitations in RbFe2F6 ¿ A possible S=5/2 Kagome lattice?
We propose to investigate the spin fluctuations in a candidate S=5/2 Kagome lattice. Previous neutron diffraction has found that RbFe2F6 maybe a good realization of a Kagome... -
Magnetic excitations in mesoporous hematite
We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One... -
Melting point dynamics of Confined fluids
This proposal aims to investigate the dynamics of the melting transition in H2O and CO2 when confined in a vycor (SiO2) matrix. The field of fluids in confined geometries is... -
Spin excitations in an alternating quantum spin chain
We propose to measure the magnetic excitations in malachite, a mineral that contains S=1/2 alternating chains with an alternation parameter of J'/J=0.5, just in the middle... -
Magnetic excitations in a pure Fe3+ pyrochlore lattice (FeF3) ¿ A classic spi...
We propose to study the powder averaged spin fluctuations in a S=5/2 pryochlore - FeF3. Previous studies, corroborated by our own diffraction work on WISH, have measured that... -
INS on a 2D quantum spin liquid candidate material without structural disorder.
The ordered double perovskite Sr2CuWO6 is a quasi-two dimensional J1/J2 frustrated square lattice model antiferromagnet. The divalent Cu carries S = 1/2 while the W (VI) is 4d0.... -
Kond scale of CeRh1-xIrxIn5 with x= 0, 0.25, 0.3, 0.5, 0.8 and 1
The non conventional d-wave superconductivity in Heavy Fermion compounds seems to be triggered by spin fluctuations, which is in strong contrast to conventional... -
Study of the protein denaturation in glassy matrices
The proposed experiment is addressed to use the MARI spectrometer to study the thermal denaturation process of the psychrophile enzyme alpha-amylase in presence of bioprotectant... -
Discrete breathers in the high-temperature vibrational spectra of alkali halides
Inelastic neutron measurements on some selected polycrystalline alkali halides (namely LiBr, LiI, NaBr, NaI), where the mass difference between anions and cations is large, are... -
Persistent geometrical frustration in the distorted spinel lattice
The corner-shared network of tetrahedra is the most well-known lattice exhibiting geometrical frustation of AFM exchanges under cubic symmetry. Even when the lattice symmetry is...
