Ultrafast observation of critical nematic fluctuations and giant magnetoelastic coupling in iron pnictides

CCQCN member Prof. I. Perakis in collaboration with a group of researchers, published a significant article in Nature Communications, entitled "Ultrafast observation of critical nematic fluctuations and giant magnetoelastic coupling in iron pnictides".
For this work, the researchers used time-resolved polarimetry to reveal critical nematic fluctuations in unstrained Ba(Fe1−xCox)2As2.
