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... -
INS studies of copper sulphate pentahydrate - two birds with one stone.
Copper sulphate pentahydrate is one of the iconic substances of chemistry. The characteristic dark blue colour is the result of the water present: four molecules are coordinated... -
Anomalous spin diffusion in 2D percolating magnet
This proposal is to observe single-spin diffusive motion on a two-dimensional (2D) percolating network having a fractal geometry. The random walker¿s travel times on a... -
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... -
Probing the magnetic structure of transition metal pyrovanadate Fe2V2O7
We have synthesized and characterized a new member, namely Fe2V2O7 in the family of 3d transition metal pyrovanadate M2V2O7 (M =Mn, Fe, Co, Ni, Cu). M2V2O7 exist with a great... -
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...
