Tracking changes in the phonon density of states in differently coated LixFeP...
LiFePO4 (LFP) is a commercially used Li ion battery material for high power applications. Particle shape and surface play an important role in the Li diffusion and thus the... -
Probing hybridization strength and homogeneity of valence mixing in magnetica...
The compounds we want to study belong to the well-known tetragonal RM2X2 family (R: rare earth, M: d element, X: Ge, Si). In EuCu2(SixGe1-x)2, the Eu valence changes, as a... -
Magnetic fluctuations in an FeSe superconductor (Tc = 40K) intercalated with ...
Superconductors have many practical applications, especially in technologies that require high magnetic fields, such as magnetic resonance imaging (MRI). Efforts to find new and... -
High-energy excitations in a spin orbital liquid on the diamond lattice
This proposal is part of our research programme on spin and orbital order in frustrated systems. The spinel FeSc2S4 realises an exotic ¿spin-orbital liquid¿ with no magnetic or... -
Crystal field and spin-wave excitations in the quasi-2D honeycomb zigzag anti...
The microscopic origin of the zigzag magnetic ground state in a honeycomb lattice of the quasi-2D antiferromagnet Na2Co2TeO6 is debatable. The zigzag phase may occur due to (i)... -

The coupling of spin and charge correlations in La2-xSrxCuO4
Charge density wave (CDW) order has recently been established as a generic feature of high-temperature cuprate superconductors. It occurs near 1/8 doping and has been observed... -
Alkali ions dependent collective excitations in borate glasses
Recently, it has been suggested that the First Sharp Diffraction Peak (FSDP) in glasses arises from a quasi-periodicity of void spaces in the structure, that plays the role of... -
Exploring high energy nematic spin correlations in uniaxial-strained BaFe2As2
Electronic nematic phase in iron-pnictide superconductors have been discovered in various systems by techniques such as resistivity, ARPES, magnetic torque and neutron... -
Study of a spin gap and CEF excitations in the caged compounds CeT2Al10 (T=Fe...
This proposal was submitted on MERLIN (RB1010206) and beam time was allocated on MARI. We have carried out low energy measurements on MARI and found a clear evidence of the spin... -
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... -
Search for Weyl Magnon in LiGaCr4O8
Weyl magnon in the chromium-based breathing pyrochlores is a recently predicted novel magnetic excitation state. Similar to its anolog, Weyl fermion in the electric systems,... -
INS as a dual-probe of giant magnetic anisotropy and vibrational density of s...
Monometallic complexes of paramagnetic transition metal or lanthanide metal ions have found to exhibit single-molecule magnet (SMM) behaviour with an appreciably enhanced... -
Spin excitations in the candidate Weyl semimetal EuCuAs
Very recently, EuCuAs was proposed as an example of a topological semimetal. Our measurements on Wish show that the Eu magnetic structure is incommensurate with a propagation... -
The search for long range exchange interactions in the S=1 square lattice ant...
Exchange interactions in insulators can be understood in terms of the Andersen exchange picture in which the Hamiltonian has two contributions: (i) a kinetic term characterized... -
Investigation of magnetic excitations of spin-chain oxides Sr4-xCaxMn2CoO9
The Sr(4-x)Ca(x)Mn2CoO9 compounds are geometrically frustrated transition metal (TM) oxide, which present a variety of interrelated magnetic behavior. The (Mn,Co) TM form a... -
Uniaxial pressure effect in FeTe
Superconductivity in iron-based materials occurs in close proximity to a long-range ordered magnetic phase. In the iron pnictides, uniaxial pressure shifts the magnetic ordering... -
An Investigation on the Effects of B-site disorder on the CF scheme of Rare E...
We propose to use MARI to (1) compare the properties of the crystal field (CF) scheme between Yb2GaSbO7 (YGSO) and its parent compound Yb2Ti2O7, in hopes of elucidating the... -
The Metal to Insulator Transition (MIT) in Bi1.7V8O16 probed with neutron spe...
We propose to investigate the low energy spin and orbital fluctuations in Bi1.7V8O16 which displays a metal to insulator transition. This work will be performed in conjunction... -
