Alpha-CaCr2O4: magnetic study of a new case of triangulaire Cr-lattice
We propose to study a layered oxide in which chromium cations describe a triangular array. Itseems us that no magnetic data are reported up to now for this alpha-CaCr2O4... -
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... -
Structural phase diagram of rare earth substituted multiferroic BiFeO3 - revi...
BiFeO3 is the most widely studied multiferroic and rare earth doping overcomes problems associated with phase metastability and leakage which have hampered applications. We... -
Nature of the ground state of Dy2Ti2O7 spin ice
Spin ice (SI) is a state of matter characterized by a residual (Pauling) entropy and unusual correlations. The huge interest in SI materials from the magnetism community stems... -
Structural Studies of Li(ND3)n11BD4
On exposure to ammonia, Li(11)BD4 forms the ammoniate Li(11)BD4(ND3)n. Our recent experiment (RB820252) has shown that there are four distinct crystalline phases in the... -
Neutron analysis of the structure of SrAl2O4 from 300 to 1273 K.
SrAl2O4 is a stuffed tridymite that has attracted a good deal of interest, since doping with Eu2+ leads to a material with elastic-luminescent response. The structure and phase... -
Quantum magnetism in lanthanide gallium garnet magnetocaloric materials
Geometrically frustrated lanthanide gallium garnets find practical applications as low temperature magnetocalorics, but the competing interactions in these materials may give... -
Structure and magnetic properties of Sr4Fe6O12
Despite many previous attempts, Sr4Fe6O12 (the expected fully reduced composition for Sr4Fe6O13-x) has not been synthesised. It is of interest because it is believed to contain... -
Completing the Magnetic Ordering-Crystal Structure Phase Diagram of Supercond...
The key objective is to measure three samples of composition Fe(1.05)Te, Fe(1.12)Te, and Fe(1.14)Te as a function of temperature (base to 80 K) through their magnetic ordering... -
Competing degenrate magnetic states in Ba1-xNaxFe2As2
Magnetic and superconducting ground states have been proposed to coexist in a relatively narrow compositional range in the so-called 122 pnictide superconductors. We recently... -
The hydration and ordering of lamellar block copolymer films prior to the for...
The key to the use of polymer vesicles as effective molecular delivery systems is in the ability to efficiently encapsulate a molecular payload within the vesicle. We would like... -

Strain effect on the magnetic ground state of the ferroelectric Ca3CoMnO6 system
The search for new ferroelectric materials, where the ferroelectricity results from magnetic frustration, has been a topic of great interest to the condensed matter physics... -
Density-driven structural transformations in calcium silicate glass
The density-driven structural transformations in the calcium silicate glass CaSiO3 will be investigated at pressures increasing to 17.5 GPa. This glass is one of a family of... -
Phase Separation and Jahn Teller Distortion in Molybdate Perovskites
Two days of beamtime on HRPD will be used to examine a family of double perovskites Sr2YbMO6 that are isostructural at room temperature. When M = Mo5+ the monoclinic perovskite... -
Incorporation of PAN-pyrene swollen micelles in crosslinked polyelectrolyte f...
We have been studying the formation of solid polymer-surfactant films at the air-solution interface formed from cationic surfactants with PEI. We wish to use the micelles... -
Crystal structures and magnetic order in metal/ammonia intercalates of FeSe
This is a proposal to determine the magnetic structures of the Rb/NH3 and K/NH3 intercalates of FeSe. These compounds exhibit superconductivity when freshly prepared, but... -
Time Resolved Studies on Inorganic Film Formation at the Air-Solution Interface
In a recent SURF experiment on the formation of silica films templated with cat-anionic/polymer complexes we found that the film growth and evolution occurs on a faster time... -
Structural Studies of PbZr1-xTixO3: completing the puzzle in the tetragonal a...
We request 6 days of HRPD time in order to study the structures on the tetragonal side of the lead zirconate-titanate (PZT) phase diagram, a region that has so far been rather... -
Zr-based metal-organic frameworks as carbon-free energy carriers: a study of ...
Structural information of Zr-based MOFs including UiO-67, m-UiO-67, and UiO-bpydc upon ammonia loading will be investigated by an in situ neutron powder diffraction technique....
