Magnetic neutron diffraction study of Ba(Fe1-xCox)2As2 critical exponents through the tricritical doping

D. M. Pajerowski, C. R. Rotundu, J. W. Lynn +1

We present temperature dependent magnetic neutron diffraction measurements on Ba(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$ for $x$ = 0.039, 0.022, and 0.021 as-grown single crystals. Our i…
