A Self-consistent Description of the Thermoelastic Properties of Dielectric P...
20 years ago, Anderson proposed that the thermoelastic properties of the dominant (mantle) phase within the Earth, MgSiO3 perovskite, could be described as a simple Debye solid.... -
Multiferroic (Ferroelastic/Magnetic) Phase Transitions in KMnF3
KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling... -
Structure and phase transitions of Sr3Ru2O7
Sr3Ru2O7 is a layered Ruddlesden-Popper perovskite which displays intriguing behaviour at low temperatures and high magnetic field. It can be tuned close to a quantum critical... -
Understanding the ground state wavefunction in PrPtAl and YbNiSn
The proposal addreses the compounds PrPtAl and YbNiSn. Both systems are canted ferromagnets with both materials undergoing moment reorientation transitions as a function of... -
Study of magnetic spiral in the room temperature multiferroic BiFeO3 - PbTiO3
BiFeO3 is a room temperature multiferroic, displaying both ferroelectric and antiferromagnetic (AFE) ordering. x-BiFeO3 - (1-x)-PbTiO3 is also multiferroic at room temperature... -
Magnetism and structural distortions in the Sr(2-x)Ba(x)NiOsO6 system
The magnetism of double perovskites can be amazingly sensitive to subtle distortions of their structures. Previous studies have shown that Ca2NiOsO6 is a ferrimagnet, Sr2NiOsO6... -
Magnetic structure and multiferroicity in metal-formate perovskites
The family of guanadinium metal formates (M=Mn, Fe, Co, Ni, Cu) are isostructural with the perovskites and are therefore of interest for potential applications: in particular,... -
Neutron Diffraction study of Highly Frustrated SrEr2O4
We propose to measure the neutron diffraction pattern of a single crystal sample of SrEr2O4, using the WISH diffractometer. As the magnetic Er ions in this compound are linked... -
Neutron diffraction and µSR investigation on YbPd
YbPd crystallizes in the cubic CsCl-type structure and reported to have magnetically ordered ground state with the mixed valence of the Yb ion. Further, it under goes through... -
Spin waves in lightly doped LiGa1-xInxCr4O8
Magnetic frustration - the inability to mutually satisfy all magnetic interactions in a system - is the source of many interesting phenomena, including spin liquids and ices. In... -
Inelastic Neutron Scattering study on Co-doped CeCu2Ge2
The AFM ground state of CeCu2Ge2 can be continuously suppressed by Co doping and NFL type behavior is seen around the critical concentration xc = 0.6. The electrical resistivity... -

Investigation into the reversibility of TiCl4 doped NaALH4
Hydrogen Storage still remains the technology bottleneck for a more widespread use of hydrogen. Solid complex hydrides such as amides, alanates and borohydrides have been... -
Proton dynamics in novel organic ferroelectric materials
The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in...
