NSD
Position structure from a measurement at 173K
Structure under a 6T magnetic field along z.
The structures of two other phases without field are also reported (see #0.426 amd #2.50)
Values for the Mn and Eu moment moduli were not refined. The refinement had only only as free parameter the angle of the Eu moments on the xz plane with respect to x (angle: 9.3(9)).
Eu moment components given here with non-significant digits in order to yield the moment modulus fixed in the model.
