Understanding the barocaloric effect in Mn3NiN using inelastic neutron scatte...
Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Whilst magnetocaloric... -
Spin dynamics in the zig-zag ladder beta-CaCr2O4
We propose to investigate the spin dynamics in the frustrated antiferromagnet beta-CaCr2O4. Its structure consist in one dimensional chains of Cr+3 forming the legs of zig-zag... -
Spinwaves excitations in the zigzag spin chain compound beta-CaCr2O4
The S=3/2 zigzag chain antiferromagnet beta-CaCr2O4 exhibits broad spinwave excitations at low temperature, related to an incommensurate magnetic order that sets at TN = 21K.... -
Magnetic excitation in triangular latticce antiferromagnet alpha-CaCr2O4
The triangular Heisenberg antiferromagnet is the classic example of the frustrated magnet, here the ground state forms a non-collinear 120° structure. A number of different... -
Low temperarature structure of Sr2CoO2Cu1.85S2
This proposal aims to exploit the superior flux on the upgraded HRPD coupled with the intrinsic high resolution to examine the differences between a sample of Sr2CoO2Cu1.85S2... -
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...
