Spin excitations in the paramagnetic phase of a charge-ordered bilayered mang...
In a previous experiment we measured the spin wave spectrum of the half-doped bilayer manganite Pr(Ca,Sr)2Mn2O7 in its spin, charge and orbital ordered phase. The data, which... -
Magnetic and Nuclear Structures of Low-dimensional Antiferromagnet K(1-δ...
In 2010 several groups showed that iron selenide, already a superconductor at 8 K, could be charged with alkali cations leading to higher critical temperatures. These compounds... -
Strain analysis of commensurate charge order/zener polaron ordering transitio...
High resolution powder diffraction data will be used to obtain lattice parameter and atomic coordinate variations as a function of temperature for Pr0.6Ca0.4MnO3, which has a... -
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... -
Study of structural phase transition in the spin-dimer YbAl3C3 using high res...
YbAl3C3 undergoes a structural phase transition at 80 K and a spin-dimer formation below 10K. To gain more information on the nature of the spin-dimer state and the phase... -
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... -
Investigating proximity effect in tunneling geometry across STO insulator in ...
Recently a number of studies have been reported in FM/SC multilayers on proximity effect. Taking a step forward we propose to study coupling of SC and FM layers through an... -
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... -
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,... -
Inelastic neutron scattering study of exchange disorder in CaFe2O4 and CaFe1....
We would like to investigate polycrystalline CaFe2O4 which undergoes two magnetic transitions to a B phase below 190 K and to a A phase below 160 K. Both phases coexist in a... -
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... -
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...
