Neutron texture investigations of hard magnetic Mn-Al bars

In the present work connections between magnetic properties and texture of two samples of the tetragonal MnAl phase are investigated. For texture studies classical angle dispersive neutron diffraction and neutron time-of-flight method have been applied. The process of specimen preparation is briefly described. The mathematical treatment of experimental data for complete texture analysis has been outlined. The texture of investigated samples is weak. Some main components in inverse pole figures are inclined with respect to the direction of easy magnetization. In this way the non-optimal magnetic properties of the investigated material can be explained. (author)
