In-plane uniaxial pressure-induced out-of-plane antiferromagnetic moment and critical fluctuations in BaFe${}_2$As${}_2$

Panpan Liu, Mason L. Klemm, Long Tian +13

A small in-plane external uniaxial pressure has been widely used as an effective method to acquire single domain iron pnictide BaFe${}_2$As${}_2$, which exhibits twin-domains without u…
