“…In this context, techniques for data processing continually concentrate efforts on miniaturization using templates or applying external fields (Grzelczak et al 2010); however, the magnetic recording remains the leading technique procedure for mass data storage (Tian et al 2015). Nowadays, the magnetic properties of nanoscale materials require special attention because of their potential contribution to the development of high-density magnetic storage media (Xiang & Chen, 2017). Apart from this, another challenge for developing instrumentation systems is to enhance readable properties, thereby decreasing mechanical degradation phenomena for as long as possible.…”

This study explores magnetization exhibited by nanoscale platinum-based structures embedded in pure silica plates. A superposition of laser pulses in the samples produced periodic linear arrangements of micro-sized structures. The samples were integrated by PtO2 microstructures (PtOΣs) with dispersed Pt oxide nanoparticles in their surroundings. The characterization of the materials was performed by high transmission electron microscopy studies. Furthermore, topographical and magnetic effects on the sample surfaces were analyzed by atomic force microscopy and magnetic force microscopy, respectively. The magnetic measurements indicated an enhancement in the gradient phase shift and in the gradient force related to the magnetic PtOΣs. The possibility of tuning the magnetic characteristics of the samples through contact with a Nd2Fe14B magnet was demonstrated. This process corresponds to an innovative method for obtaining magnetic PtOΣs induced by laser pulses. Moreover, an increase in the compactness of the silica with platinum-based structures was confirmed by an evaluation of the effective elastic modulus with reference to pure silica. The multimodal magnetic structures studied in this work seem to be candidates for developing high-density magnetic storage media.
