Magneto-optic phonon resonances in magnetic topological EuCd2As2 via helical Raman spectroscopy

Jin Ho Kang, Liangbo Liang, Ioannis Petrides +6

EuCd2As2 materials have two magnetic ordering states: antiferromagnetic (AFM) and ferromagnetic (FM) when their chemical tunability is utilized. While AFM-EuCd2As2 has a nonzero ma…
