Low-energy spin excitations in Ni over-doped NaFe0.7Ni0.3As
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.... -
Spin excitation in magnetic Weyl semimetal HgCr2Se4
Topological materials get extensive attention in last three decades. HgCr2Se4 is one of those materials being a Weyl semimetal which is induced by time-reversal symmetry...
