Coexistence of ferromagnetic and stripe-type antiferromagnetic spin fluctuations in YFe${}_2$Ge${}_2$

Hongliang Wo, Qisi Wang, Yao Shen +18

We report neutron scattering measurements of single-crystalline YFe${}_2$Ge${}_2$ in the normal state, which has the same crystal structure to the 122 family of iron pnictide supercond…
