Research Abstract

In order to clarify the change of complex magnetic order toward the quantum critical point(QCP) and, as our final goal, the specific properties of the superconductivity near-neighbor to QCP in noncentrosymmetric CeCoGe_3, Co-NQR/ NMR measurements under pressure have been performed. The emergence of the complex magnetic order, successive magnetic transition accompanied by the step-like decrease of the magnetization, is confined to the low pressure below about 0. 7GPa. The magnetic structure in higher pressure becomes a variation of the type uudd ever proposed by the neutron scattering experiments in ambient pressure. The magnetic order-pressure phase diagram toward QCP is deduced.
