Magnetic and acoustic properties of CoCr₂S₄
We report results of magnetic and ultrasound studies of the sulfide spinel CoCr₂S₄, for which the multiferroicity has recently been suggested. Clear anomalies in the magnetic and acoustic properties have been observed at TN = 222 K and in applied magnetic fields evidencing the important role of magn...
