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... -
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... -
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... -
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... -
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... -
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... -
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... -
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,... -
