Neutron Diffraction Study of a Spin-1/2 Pyrochlore Lu2Mo2O5N2
Ammonolysis of R2Mo2O7 pyrochlores gives R2Mo2O5N2 containing S = ½ Mo5+. They are excellent candidate materials for investigation of quantum spin liquid phenomena and we have... -
Anion order in perovskite oxynitrides
Transition metal oxynitrides with perovskite type structures are an emerging class of materials with optical, photocatalytic, dielectric and magnetoresistive properties that may... -
Spin dynamics in disordered La(Cr1/3Mn1/3Fe1/3)O3 perovskite.
Disorder of magnetic cations usually suppresses long-range spin order: the Curie or Néel temperature drops rapidly, and a spin glass state often results at high disorder levels.... -
Exploring magnetic correlations in a new S=1/2 kagome antiferromagnet
The combination of strong magnetic frustration and low spin found in the S=1/2 quantum antiferromagnet is believed to lead to non-classical magnetic behaviour, and in particular... -
Variable temperature study of frustrated magetism in Lu2Mo2O5N2
Geometrically frustrated S= 1/2 magnets are of great interest as they do not show classical long range magnetic order at low temperatures and can adopt exotic quantum spin... -
MuSR Study of Magnetically Frustrated Lu2Mo2(O,N)7 pyrochlores
The combination of magnetic frustration and low magnetic moment leads to non-classical magnetic behaviour such as spin liquid states. We have prepared polycrystalline samples of... -
Anion correlations in Ta oxynitrides
Transition metal oxynitrides with the perovskite structure type are an emerging class of functional materials with a variety of interesting optical, photocatalytic, dielectric... -
Structural evolution in LiVS2 anode materials
Intercalation electrodes operating close to 1V vs. Li+/Li are highly desirable. They are safe and provide protection to plating Li if overcharged, while still giving a... -
Short range magnetic order in the compositionally modulated Bi2Cr4/3Ni2/3O6 p...
It is particularly challenging to synthesize a novel multiferroic material as it seems that the mechanisms that allow ferromagnets and ferroelectrics to work are mutually...
