摘要
Changes in hysteresis loss of Terfenol-D rods due to compressive stress have been investigated to clarify its characteristics. The hysteresis loss monotonically increases owing to compressive stress, and its increment is in proportional to mechanical work of magnetostriction under compressive stress. The proportionality ratio between them relates to the increment of non-180degrees walls due to compressive stress in magnetization process. (C) 2002 Elsevier Science B.V. All rights reserved.
