Adjusting microstructure and magnetic properties of Ni-Mn-ln Metamagnetic Shape Memory Alloys by addition of Gd

摘要

The influences of Gd concentration on martensitic transformation and magnetic properties of NiMnln alloys were investigated by differential scanning calorimetry (DSC) , vibrating sample magnetometry (VSM), X-ray diffraction (XRD) and etc. It shows that addition of Gd enhances martensite transition temperature and that X-ray diffraction analysis of experimental alloys is revealed which the mixture is martensite and austenite at room temperature. These alloys show promise as a metamagnetic shape memory alloy with magnetic-field-induced shape memory effect.
