Data were obtained from the spectrometer EIGER at PSI

Experimental set up
ki=kf=2.662 A-1
We used the MA15 magnet with a rotating unit. 
Q-scans as a function of field and temperature. 

Sample
small cuboid single crystral on Al pin : 0.5x1.5x2.5 and weight 66 mg
Sample parameters are the following : a=b=7.05 A, c=3.99 A, alpha = beta = gamma = 90.
The sample is aligned with (100) and (010) in the scattering plane. Magnetic field applied
along (001)
