Structural and magnetic properties of novel Fe1.5VGe and parent Fe2VGe alloys

Abstract

The present study explores the structural, morphological, and magnetic characteristics of the Fe1.5VGe Heusler alloy, which has not been previously reported in the literature. The sample was characterized using Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), and a Physical Property Measurement System (PPMS). An L2₁-type crystal structure, consistent with the existing literature, was observed through the analysis of XRD measurements. SEM images showed crack-like features and pores on the surface. Almost no coercivity was observed in the field-dependent magnetic measurements (M-H) conducted at constant temperatures of 5 K and 300 K. The 5 K (M-H) measurement showed easy saturation without requiring high fields. This result suggests that the Fe1.5VGe sample could be a promising candidate for industrial applications, especially in electronics.
