Magnetic properties of NdCuGa₃ single crystals

The study of magnetic order in the f-electron system has received significant attention due to the finding of exotic magnetic phases of matter. The detailed low-temperature physical and magnetic characterization is critical for revealing an exotic magnetic ground state. This presentation will discuss the low-temperature magnetic properties of NdCuGa3. NdCuGa3 crystallizes in a tetragonal crystal structure with C_4v symmetry. It exhibits an antiferromagnetic phase below TN = 3.5 K, and no additional phase transition was detected down to 50 mK zero-field specific heat measurements. The nature of the antiferromagnetic phase is expected to have incommensurate magnetic ordering. The presentation includes the detailed structure, magnetic, and physical properties of NdCuGa₃.
