Both the hysteresis loop and the anisotropy field of nanocrystalline Pr12Fe
82B6 were measured as function of temperature in a pulsed field system. Sup
plementary three-dimensional neutron depolarization experiments were perfor
med with the same sample in order to determine its mean domain size and to
reveal an eventual magnetic texture. (C) 2001 Elsevier Science B.V. All rig
