Claims

C1strongest claim

We identify this material as a collinear ferromagnet (hex-FM) with uniform moment length mc = 2.1 μB/Nd and ordering vector Q = 0, in contrast to a previous, seminal report that proposed unequal moment lengths on two Nd sites.

C2weakest assumption

That the observed neutron intensities and polarized flipping ratios are produced solely by the hex-FM structure and are not significantly affected by domain populations, extinction effects, or minor impurity phases.

C3one line summary

Nd3Ru4Al12 is a collinear ferromagnet with uniform Nd moment length of 2.1 μB and ordering vector Q=0, not the previously proposed state with unequal moments on two Nd sites.
