Spin-phonon interaction and mode softening in NiF₂
The temperature dependence of the four Raman-active phonons in NiF₂ is investigated at temperatures above and below the antiferromagnetic ordering temperature of TN=73 K. All four modes exhibit distinct anomalies in their intensities and frequencies near TN due to spin–phonon coupling. The phonon li...
