Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Whilst magnetocaloric... -
Spin Waves at High Temperature in the Parent Compound of the Superconductor F...
The recently discovered iron based superconductors have transition temperatures second only to the cuprates. The majority of these compounds display superconductivity after... -
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... -
Low-energy spin excitations in Ni over-doped NaFe0.7Ni0.3As
The discovery of iron-based superconductors gives a new horizon to study unconventional superconductivity. Typically iron-based superconductors can be created by doping (i.e.... -
Spin wave investigation in brownmillerite oxygen deficient perovskite Ca2Fe2O5
The Dzyaloshinskii-Moriya interaction is thought to be responsible for the stabilization of weak ferromagnetism or magnetic spiral states in a number of diverse systems. An... -
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... -
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... -

SMMs have received much attention owing to their quantum tunneling and slow relaxation of the magnetization. This has led to an intense activity by synthetic chemists to... -
Crystal field excitations in SrTb2O4
SrTb2O4 belongs to the family of rare-earth RE strontium oxides, SrRE2O4. These compounds, consisting of hexagons and triangles, are affected by geometrical frustration and... -
CEF scheme investigation of selected CenTmIn3n+2m (T=Rh, Pt) compounds
Due to the tunable interplay between magnetism and superconductivity the CenTmIn3n+2m (n, m = 1, 2; T = Co, Ir, Rh, Pd, Pt) family of heavy fermion compounds has been attractive... -
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... -
Coupled magnetic and nematic fluctuations in S-doped FeSe
Iron selenide (FeSe) is the simplest of the iron-based superconductors. It has a nematic (tetragonal to orthorhombic) phase transition at T = 90K. Upon doping with sulphur, the... -
Magnetic interactions in the room-temperature skyrmion material Co8Zn8Mn4
We propose an investigation of the spin-waves in the recently discovered room-temperature skyrmion material Co8Zn8Mn4. The ground state of Co8Zn8Mn4 is a very long wavelength... -
