Full reciprocal space mapping of the relaxational dynamics in CH3NH3PbCl3:
The organic-inorganic perovskites with chemical formula CH3NH3PbB(Br,Cl,I)3 have been implicated as being efficient photovoltaic materials. Theoretical calculations and... -
Nearly ferromagnetic fluctuations in CeRhSi3? A high resolution study at lo...
The proposal requests time on OSIRIS to measure the low-energy magnetic fluctuations in CeRhSi3. This compound is a noncentrosymmetric superconductor under pressures of ~10... -
Magnetic excitations in Strontium Erbium Oxide
In SrEr2O4 the magnetic Er ions are linked through a network of triangles and hexagons, where geometrical frustration can arise, provided that some exchange interactions are... -
Fractionalized spin excitation and crystal electric field study in the rare-e...
A new rare-earth triangular quantum spin liquid (QSL) candidate, YbMgGaO4, has an odd number of electrons per unit cell and spin-orbit entangled effective spin-1/2 (Yb3+).... -
Unveiling the exotic quantum critical point in CeCu6-xAgx
The heavy fermion system CeCu6-xAux is arguably the most important (and studied) heavy fermion series which exhibits a quantum critical point. In recent years several new... -
Spin dynamics in the extended Kagome system YBaCo4O(7+x)
A recently discovered new class of geometrically frustrated magnets is the family of cobalt oxides RBaCo4O7 (R=rare earth or Y). The structure is built up CoO4 tetrahedra which... -
Investigation of bilinear magnetoelectric effect in magnetic field-induced mu...
We propose to perform a neutron diffraction experiment under magnetic fields using a single crystal sample of multiferroic alpha-NaFeO2 on WISH beamline. Recently, we have... -
Critical and quantum critical spins fluctuations in URhGe
Ferromagnetism in URhGe is continuously suppressed with a magnetic field leading to a Quantum Critical Point (QCP) at around 12 T engulfed by a pocket of superconductivity. The... -
Spin dynamics in the 1/3rd magnetization plateau phase of a triangular quantu...
This experiment is part of our research programme to explore novel quantum phases and phase transitions induced by magnetic field in frustrated quantum magnets. The quasi-2D... -
Magnetic field diffraction study of Gd2Ti2O7
We propose a study of the magnetic structure of isotopically enriched Gd2Ti2O7. We have successfully grown and characterised large single crystals using low-absorption 160Gd. In... -
Quantum Criticality in YFe2Al10
Quantum phase transitions, where correlation length and time scales diverge, are of broad interest to the condensed matter physics community. The new layered material YFe2Al10... -
What is the cause for the gapped mode in the `BEC' phase of DTN?
Arguably the most-famous quantum phase transition is the Bose-Einstein condensation (BEC) of magnons. It can be studied experimentally in gapped quantum paramagnets when an...
