Influence of the cation disorder on the magnetic properties of underdoped cup...
We want to isolate the effects of doping, charge localization and local distortion on the transition from insulating antiferromagnet to superconducting metal in YBCO. We choose... -
Spin Dynamics in Organic-Inorganie Hybrid Systems
The organic-inorganic hybrid systems consist of organic and inorganic components forming a 2 D layered structure. The distance between adjacent magnetic layers is quite far,... -
Structural distortions and magnetism in the layered oxide sulfide Sr2MnO2Cu1.5S2
This proposal aims to exploit the superior flux on the upgraded HRPD coupled with the intrinsic high resolution to correlate the magnetic structure and the crystal structure of... -
Search for structural modulation lifting the orbital degeneracy in triangular...
This proposal is part of our research programme on spin and orbital order in frustrated systems. AgNiO2 has a layered crystal structure with Jahn-Teller active Ni3+ ions forming... -
Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such...
