Orientation Relationship Between Magnetic Domains and Twins in Ni52Fe17Ga27Co4 Magnetic Shape Memory Alloy

摘要

The orientation relationship between magnetic domain and twins in the directional solidified Ni52Fe17Ga27Co4 magnetic shape memory alloy was analyzed by electron backscatter diffraction and magnetic force microscopy. The twin interface plane was determined to be plates. The magnetic domains walls with a misorientation about 5 deg belong to low angle boundaries. According to the orientation relationship between twins and magnetic domains, the intersection angle on the observed surface can be estimated.
