Ex situ Study of glass formation from Cu-exchanged Zeolite by INS
In the earlier research, the rheology of collapsing zeolites amorphized by temperature has been studied as well as the vibration that destabilize crystals. With the study of... -
Neutron Spin resonance in the Fe-based silicide superconductor LaFeSiH
The iron-based superconductors (Fe-SC) are one of the most active and challenging topics in condensed matter physics. Very recently some of us (F. Bernardini et al.) have... -

The Heisenberg antiferromagnet is a well-known model used to describe the magnetic properties of layered and metal-organic Mott insulators which have been explored both... -
Exchange interactions and spin gap in Cu2PO4OH
The mineral Libethenite, Cu2PO4OH, is an ideal system in which to study low dimensional quantum magnetism. Its magnetic behaviour is complex but is related to systems with... -
Spin excitations in the non-magnetic ground state of In2Ru2O7
Correlated transition-metal oxides with orbital degeneracy such as ruthenates with d4 (S = 1) configuration offer a plethora of unconventional electronic states. Combined with... -
Spin-orbit transitions in CoV3O8
Strong orbital mixing resulting from local distortions in the crystal field can mix higher energy orbital states with the ground state. We propose to characterise this mixing in... -
