This book was written in the hopes that readers, particularly young researchers and students, would be able to learn more about how Argon ion irradiation affects multilayer thin film systems, with a focus on Fe/Si metal-semiconductor systems, and how it is linked to magnetoresistance (MR) properties. This issue is significant because it covers the phenomena of physical characteristics, which are crucial in comprehending MR phenomena at the nanoscale scale. The Helicon Sputering technique is used to create thin films with thicknesses in the nanoscale range, a technology that allows for extremely precise film creation. Furthermore, it can be demonstrated that ion irradiation has an effect on MR characteristics, which can be linked to the interfacial structure between the Fe and Si layers. Several characterization techniques, such as Conversion Electron Mossbauer Spectroscopy (CEMS), Rutherford Back Scattering (RBS), and confirmation with Vibrating Sample Magnetometer(VSM) and Four Point Probe(FPP) for the magnetic and MR properties of post-irradiated thin film systems, can clarify this effect. This book can add to our understanding of how ion irradiation alters the physical properties of thin films and reduces the sensitivity of thin-film sensors like magnetic sensors.
The book is divided into five chapters, the first of which is an introduction to the current state of research on the GMR phenomena in multilayer Fe/Cr and Fe/Si. In Chapter 2, we discussed the basic theory of GMR in multilayer and exchange interactions, as well as the synthesis process of Helicon plasma Sputtering. In Chapter 3, we discussed the materials, synthesis methods, and characterization of multilayer films. In Chapter 4, we went through the pre-irradiation and post-irradiation of Argon ions in relation to the Fe/Si multilayer and its structure model in great depth. The conclusion concerning the influence of ion irradiation on the structure and magnetic characteristics of multilayer Fe/Si is found in Chapter 5.Author(s) Details
