Magnetic Order and Magnetostructural Coupling in BaCrFeAs2 and BaCr2As2
We propose to study the magnetic order and temperature dependent structural properties of the ThCr2Si2-type phases BaFeCrAs2 and BaCr2As2 at instruments E9 and E2. These... -
Coexisting incommensurate magnetic phases in oxygen-deficient SrFeO3-x
Recently we have carried out a comprehensive study of the crystal structure and magnetic order in SrFeO3-x [1] and Sr3Fe2O7-x [2,3]. In contrast to the magnetic phases of SrFeO3... -
p-orbital magnetism in cesium superoxide
CsO2 is the most interesting of the alkali superoxides. It shows a remarkable variation in the magnetic exchange coupling J(T) of over 50%. An orbital ordering transition occurs... -
Step like relief of “geometric frustration” on the distorted pyrochlore Cr-su...
In the system Ni1-xCuxCr2O4 competing Jahn-Teller distortions combined with geometrical frustration give rise to a rich phase diagram as a function of x(Cu) and temperature. Now... -
Commensurate and incommensurate magnetic phases in oxygen-deficient SrFeO3-x
The present proposal on SrFeO3-x is motivated by our recent inelastic neutron scattering measurements, where three incommensurate magnetic phases with propagation vectors k2 =... -
Investigation of the role of Ti and Cu doping on the crystal structure and ma...
In the current proposal we would like to investigate the nature of magnetic ordering and crystal structure of Ti and Cu doped ferrimagnetic spinel MnCo2O4 using the powder... -
Study of magnetic ordering in the inverted spinels Co2TiO4 and Co2SnO4
In the present study we like to investigate the nature of magnetic ordering in Co2TiO4 and Co2SnO4 materials using the powder and single-crystal neutron diffraction technique.... -
Incommensurate magnetic ordering in the geometrically frustrated system Ni1-x...
Only recently, we have investigated in detail the evolution of the structural and magnetic phase transition temperatures of the system Ni1-xCuxCr2O4. Competing Jahn-Teller...
