Nanoscale analysis of magnetic properties of graphene nanoribbons (GNRs) conjugated with magnetic nanoparticles has been studied in this work. The effect of varying concentrations of and Ni nanoparticles on the magnetic domain structure of GNRs has been investigated using magnetic force microscopy (MFM). A variable external magnetic field was applied to the samples, and an evident variation in the domain structure with a change in the magnetic field was observed. It was found that magnetic properties and the imaged magnetic domain structure are influenced by the concentration of magnetic nanoparticles conjugated with GNRs. The vibrating sample magnetometry (VSM) studies support the nano-domain studies done using MFM such that the trend observed for the saturation magnetization obtained from vibrating sample magnetometry (VSM) matches that of the phase difference obtained using MFM.
Magnetic force microscopy study of induced magnetism in graphene nanoribbons influenced by magnetic nanoparticles
Sadly, Dr. Ashutosh Abhyankar passed away in May 2021. As he was an integral part of this work, after the completion of the study, the rest of the authors decided to submit the paper with his name as a coauthor.
Note: This paper is part of the Special Collection Recognizing Women in Applied Physics.
