Anomalous resistivity upturn in the van der Waals ferromagnet Fe${}_5$GeTe${}_2$

Yalei Huang, Xinyu Yao, Fangyi Qi +2

Fe${}_5$GeTe${}_2$ (n = 3, 4, 5) have recently attracted increasing attention due to their two-dimensional van der Waals characteristic and high temperature ferromagnetism, which make…
