Giant spin fluctuations and their effect on the first order magnetic transiti...
A giant enhancement of the heat capacity in La(Fe13-xSix) indicates the presence of large spin fluctuations at the paramagnetic to ferromagnetic phase transition. The nature of... -
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... -
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... -
Inelastic neutron scattering study of PrTSi3 (T = Ir, Rh and Ru)
Recently we have synthesized and investigated three new ternary intermetallic compounds PrTSi3 (T = Ir, Rh and Ru) which form in BaNiSn3-type tetragonal structure (space group... -
Inelastic neutron scattering study on new Mott-insulating oxychalcogenides, L...
La2O2M2OSe2 (M=Fe, Co, Mn) are layered Mott-insulating antiferromagnets with a potential to be a non-copper high-Tc superconductor. All compounds have shown unusual magnetic... -
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... -

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.... -
Inelastic Neutron Scattering study on PrRhSn3
Recently we have investigated the cubic compound PrRhSn3 using the dc and ac susceptibilities and the heat capacity. We found an evidence for the cluster-glass behavior with a... -
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... -
Investigation of the temperature dependence of Q-dependent vibrational modes ...
This proposal seeks to measure the poly-CINS (polycrystalline coherent inelastic neutron scattering) spectrum from magnesium deuteride (MgD2); a powder sample on the MARI... -
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... -
