Full reciprocal space mapping of the relaxational dynamics in CH3NH3PbCl3:
The organic-inorganic perovskites with chemical formula CH3NH3PbB(Br,Cl,I)3 have been implicated as being efficient photovoltaic materials. Theoretical calculations and... -
Spin dynamics in quasi-2D frustrated triangular lattice S=2 antiferomagnet Fe...
We propose to map a vast swathe of Q-E space in four temperature regimes of FeGa2S4 polycrystalline sample on LET. Observation of long- and short-range dynamic spin correlations... -

Inelastic Measurements of a Frustration Stabilised 1D Ordered Magnetic State
Magnetic chains are playgrounds for unconventional physics but emergence of 1D order in cannonical systems is associated with full 3D magnetic order. Uniquely, below 1.6 K,... -
Excitation spectrum of the frustrated spinel GeCo2O4
The spinel GeCo2O4 is a promising compound to establish the consequences of geometrical frustration, as the magnetic Co2+ ions are on a network of corner-sharing tetrahedra... -
Magnetic excitations in a spin-liquid candidate K2Ni2(SO4)3
In majority of magnetic compounds interactions between spins, that reside on magnetic ions, result in a long-range ordered state below a critical temperature. In some materials... -
Magnetic coupling-scheme of {Cr10} wheels with S=9 ground state
Molecular magnetic wheels are models systems for the study of quantum coherence, finite-size effects and have been proposed as possible candidates for quantum bits. While AF... -
Magnetic inelastic scattering from dimethylammonium metal formates
The dimethylammonium metal formates (metal = Mn, Fe, Co, Ni) are metal-organic perovskite analogues of interest for potential multiferroicity. In these materials, electric... -

Magnetic field controlled quantum criticality in La2-xSrxCuO4
The application of a magnetic field offers a unique way to control a quantum critical point in some systems. For underdoped high temperature cuprate superconductors (HTS),... -
Measuring the intrinsic Density of Nanoconfined Liquids
Despite abundant research on nanoconfined liquids, determining the density, which is a key property of the liquid, remains an open problem. All the previously explored... -
Characterising the Holmium contribution to excitations in Holmium Iron Garnet
Rare-earth Iron garnets (R3Fe5O12) have been in the focus of active research for the last five decades due to properties such as magnetostriction, magneto-optical effects, as... -
Measuring magnetic excitations in K(NbO)Cu4(PO4)4
I am working on a low dimensional quantum magnet family. A member of it, KNb, is a good experimental realisation of the squarelattice. It appears that this compound has a... -
Tuning confinement potential of spinons in an Ising chain using magnetic fields
The Ising chain realises the fundamental paradigm of spin fractionalization, where locally flipping a spin creates two kinks (spinons) that can separate away at no energy cost,... -
Magnetic excitations in multiferroic hybrid perovskites
The novel electric, magnetic and multiferroic properties of the metal formate perovskites have resulted in substantial scientific attention over the past fifteen years. Their... -
Transverse field evolution of magnetic excitation spectrum in Nb1-yFe2+y
Our previous neutron scattering on C14 Laves phase compounds Nb1-yFe2+y revealed that a spin-density-wave (SDW) is masking an underlying ferromagnetic (FM) quantum critical...
