Abstract

Non-Technical abstract In most solids, for every atom within the unit cell at position (x,y,z) there is an indistinguishable atom at (-x,-y,-z). These materials are called centrosymmetric materials. However, magnetic materials where the centrosymmetry is broken, termed noncentrosymmetric materials, have attracted considerable attention in recent years owing to their potential for future nanometer-scale quantum-information technology applications. The aim of this project is to study the fundamental spin and lattice properties of noncentrosymmetric magnets using neutron scattering technique. Neutron scattering is a powerful probe that can determine the spin arrangements of the noncentrosymmetric materials, which will allow their potential use for future applications. The planned research will also train the next generation of graduate and undergraduate students at Prairie View A&M University (PVAMU) for neutron scattering measurements and data analysis. In addition, students will learn how to grow single crystals and basic laboratory skills in low-temperature physics. The joint efforts by combining the strength of PVAMU, Norfolk State University, and Rice University will develop an internationally competitive program involving both the growth of novel complex materials and neutron scattering. Technical abstract This project focuses on the synthesis and characterization of non-centrosymmetric magnetic materials such as ScTMGe (TM = Fe, Mn, Co, Ni, Cu), Mn-doped ScFeGe,
