The ternary full Heusler alloy nanoparticle Fe₂CrSi compounds were prepared using mechanical alloy method. The as-prepared sample was observed as amorphous in nature and further increases various annealing temperatures (like 700 °C, 800 °C, and 900 °C) in nitrogen gas atmosphere for 5 h in tubular furnace using quartz tube. X-ray diffraction studies confirmed the formation of Cu₂MnAl-type structure instead of the conventional L2₁ disordered structure. Through Williamson-Hall plot (W-H plot), the uniform deformation model was used to get low value of strain-induced broadening. In the surface morphology, elemental composition studies were carried out using HRSEM with EDS. The presence of Fe₂CrSi with the particle size of ~ 35 nm was also observed using high-resolution scanning electron microscopy and elemental composition study confirmed the presence of Fe, Cr, and Si. The magnetic properties of Fe₂CrSi nanoparticles were studied showing ferromagnetic behavior and low coercivity of soft magnetic nature. Half metallic ferromagnetic Heusler alloys have wide range of applications from medical imaging to data storage for its profound performance on spintronics.

采用机械合金法制备了全三元Heusler合金纳米粒子Fe ₂ CrSi化合物。所制备的样品在性质上被观察为非晶态，并且在使用石英管的管式炉中在氮气气氛中持续5 h升高了各种退火温度（例如700°C，800°C和900°C）。X射线衍射研究证实形成了Cu ₂ MnAl型结构，而不是传统的L2 ₁无序结构。通过Williamson-Hall曲线（WH曲线），使用均匀变形模型获得较低的应变诱发展宽值。在表面形貌上，使用HRSEM和EDS进行了元素组成研究。Fe ₂的存在使用高分辨率扫描电子显微镜还观察到了粒径约为35 nm的CrSi，元素组成研究证实了Fe，Cr和Si的存在。研究了Fe ₂ CrSi纳米粒子的磁性能，显示出铁磁行为和低矫顽力的软磁特性。半金属铁磁Heusler合金因其在自旋电子学上的出色性能而具有广泛的应用范围，从医学成像到数据存储。
