We would like to investigate polycrystalline CaFe2O4 which undergoes two magnetic transitions to a B phase below 190 K and to a A phase below 160 K. Both phases coexist in a...

In the pyrochlore magnet Ce2Sn2O7, we have established that a correlated disordered ground state develops below about 0.6 K, and that the Ce3+ magnetic ions have both dipole and...

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....

Pyrochlore oxides based on non-Kramers rare-earth ions, such as Pr3+ and Tb3+, are candidate materials for the formation of the Quantum Spin Ice. However, structural disorder is...

CeFe2Al10 belongs to the CeT2Al10 family (T: Ru, Os, Fe), which exhibits Kondo-insulator properties, with an unusual competition of strongly anisotropic crystal-field and...

Frustrated compounds belonging to the pyrochlore family have attracted significant interest as they can host a huge variety of exotic phases. In order to explore the rich phase...

In one-dimensional systems defects often have a profound effect on the physical properties. Therefore, the recent experiments on an archetypical S=1/2 Heisenberg...

In condensed matter physics, the search for new exotic quantum ground states has become a central theme over the past few years. Among the 3D quantum spin liquid candidates, the...
