Paper: Antiferromagnetism and crystalline electric field excitations in tetragonal NaCeO2

January 19, 2021

Our paper studying the magnetic ground state of the stretched diamond lattice of Ce moments in NaCeO2 was published today.  This paper showed that the Ce moments form a long-range ordered Neel state below ~6K, and suggest that this system presents an example of a material with a substantial J1/J2 ratio on the Heisenberg J1-J2 phase diagram on a distorted diamond lattice.
