Magneto-ionics using novel mobile ions for bio-inspired memory and computing systems

Research in the rapidly growing field of magneto-ionics, which exploits voltage-driven ion migration and redox reactions to manipulate magnetic properties, will be pursued. This approach provides a compelling alternative to conventional methods that rely on magnetic fields or spin-polarized currents, offering a pathway toward ultra-low-power control of magnetism. Magneto-ionics holds great promise for addressing critical challenges in modern information technologies, including improving energy efficiency, enhancing data security, and enabling novel device concepts for next-generation computing. To date, magneto-ionic phenomena have largely been demonstrated using a narrow set of mobile ions, such as H⁺, Li⁺, O²⁻, F⁻, OH⁻, and N³⁻.

Expanding beyond this limited ionic palette is essential both to broaden the range of material platforms and to enhance performance metrics such as ionic speed, reversibility, and stability. Thus, a key research direction will focus on exploiting new mobile ionic species capable of driving magneto-ionic effects, such as C, Si, B and S ions (for instance in Fe-C, Co-C, Ni-Si, Co-Si, Fe-B, Co-B or Fe-S systems), thereby unlocking new functionalities and paving the way toward scalable, practical applications. Research on well-known mobile species, such as O ions, but in unexplored systems, such as La(Sr)Fe(Co)O3 will be also carried out.

Among other aspects, special emphasis will be placed on bio-inspired functionalities, where ionic control of magnetism could mimic processes observed in living systems. Such approaches may lead to unconventional memory concepts and neuromorphic computing strategies, offering transformative opportunities for future information technologies.

The candidate should have a strong background in materials science, solid-state physics, or a related field, preferably with foundational knowledge of ferroic materials, magnetism, and thin-film concepts. Practical experience or a strong interest in thin-film deposition and materials characterization (structural, magnetic, and electrical) will be advantageous, supporting the development of magnetoelectric expertise during the PhD.

The candidate must be curious, adaptable, collaborative, and possess strong problem-solving skills, since the project involves designing and testing sophisticated materials beyond the state of the art.

Proficiency in data analysis, basic modelling, and scientific communication will be essential for interpreting results, troubleshooting experiments, and disseminating findings through publications and presentations. Initiative, independent learning, and teamwork are key to success in this interdisciplinary research environment.

Our research focuses on the design, synthesis, and characterization of advanced materials with tailored properties for cutting-edge engineering applications. By precisely controlling their structure at the nanoscale, we create materials with superior mechanical strength, optimized magnetic performance, and enhanced thermal stability.

We study a variety of systems, including nanowires, lithographically patterned micro- and nano-objects, mesoporous architectures, electrodeposited thin films, and nanocomposite/glassy alloys. Each offers opportunities to uncover new physical phenomena and functionalities. Sustainability and energy efficiency are guiding principles of our work, shaping both the development of materials and their envisioned applications.

In recent years, we have devoted particular attention to nanomaterials for brain-inspired memory and computing, with the aim of realizing energy-efficient, high-performance devices that bridge materials science and neuromorphic engineering.
