Investigation of magnetic structure in Ce2MgSi2 single crystal
Recent preparation of a Ce2MgSi2 single crystal allows us to investigate the physical properties of this Ce-based heavy fermion compound. Ce2MgSi2 crystallizes in the Mo2FeB2-type tetragonal structure and Ce atoms form the so-called Shastry-Sutherland lattice in tetragonal basal plane. This compound belongs to a relatively small group of materials in which the quantum critical point can be reached by varying external conditions. Moreover, the superconductivity dome was not observed near quantum critical point. Ce2MgSi2 has not been investigated using microscopic techniques, therefore the magnetic structure as well as the magnetic propagation vector stay still unknown. The proposed experiment is a first microscopic view into the magnetic structure of a material which exhibits quantum critical behavior under achievable hydrostatic pressures. The experiments under external pressure and in strong magnetic fields will be further steps in our broader investigation of Ce2MgSi2 compound.
