Special attention has been devoted to the honeycomb iridates (Na, Li)2IrO3, in which SOC, intrinsic geometric frustration, and other competing interactions favor a highly...

Superconductivity in iron-based materials occurs in close proximity to a long-range ordered magnetic phase. In the iron pnictides, uniaxial pressure shifts the magnetic ordering...

Exchange interactions in insulators can be understood in terms of the Andersen exchange picture in which the Hamiltonian has two contributions: (i) a kinetic term characterized...

The Dzyaloshinskii-Moriya interaction is thought to be responsible for the stabilization of weak ferromagnetism or magnetic spiral states in a number of diverse systems. An...

The discovery of iron-based superconductors gives a new horizon to study unconventional superconductivity. Typically iron-based superconductors can be created by doping (i.e....

This proposal was submitted on MERLIN (RB1010206) and beam time was allocated on MARI. We have carried out low energy measurements on MARI and found a clear evidence of the spin...

The recently discovered iron based superconductors have transition temperatures second only to the cuprates. The majority of these compounds display superconductivity after...

Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Whilst magnetocaloric...
