New near-zero-field magnetic material challenges spintronics paradigms: systemic implications for energy-efficient electronics and geopolitical tech competition

Indigenous worldviews often perceive magnetism as a sacred or animistic force, with materials like lodestone (*magnetic iron oxide*) holding spiritual significance in traditions from the Ainu of Japan to the Yoruba of Nigeria. The near-zero-field property of this material could be analogized to the balance sought in Indigenous cosmologies between visible and invisible forces, offering a metaphor for sustainable technology design that harmonizes with natural systems. However, the Western scientific framing strips this innovation of its cultural and spiritual dimensions, reducing it to a utilitarian tool.

The development of magnetic materials has a deep historical arc, from the 12th-century Chinese invention of the compass to the 19th-century discovery of electromagnetism by Faraday and Maxwell. The 1988 discovery of giant magnetoresistance (GMR) by Fert and Grünberg revolutionized computing by enabling nanoscale magnetic sensors, a precursor to modern hard drives. This new material’s near-zero external field echoes the 1950s development of permalloy, which balanced internal magnetization with minimal stray fields—a principle now being revisited for spintronic applications.

Cross-culturally, the concept of 'invisible forces' shaping reality appears in Hindu *akasha* (ether), Chinese *qi*, and African *nyama*, all of which describe unseen energies that structure the material world. The material’s ability to contain magnetic fields internally aligns with these traditions’ emphasis on containment and balance. However, the Western scientific narrative frames this as a 'discovery' rather than a rediscovery of ancient principles, erasing non-Western contributions to magnetic theory and practice.

The material’s near-zero external field is achieved through a combination of antiferromagnetic coupling and geometric frustration, a phenomenon where magnetic moments are arranged in a way that cancels out stray fields. This aligns with spintronics research that seeks to minimize energy loss in information processing, potentially reducing the carbon footprint of data centers by 30-50%. The stability above room temperature suggests compatibility with existing semiconductor fabrication processes, though long-term reliability studies are needed.

Artistically, the material’s properties evoke themes of invisibility and containment, reminiscent of works like James Turrell’s light installations or Anish Kapoor’s void sculptures. Spiritually, it challenges the Western binary of visible/invisible, material/spiritual, offering a metaphor for the integration of technology with holistic worldviews. However, the scientific community’s dismissal of artistic and spiritual interpretations risks impoverishing the discourse around such innovations.

Future scenarios include a 2035 transition to spintronic-based computers that consume 50% less energy than silicon-based systems, but this could exacerbate e-waste if not paired with circular economy policies. Geopolitical tensions may arise as nations compete for control over rare earth supply chains, particularly dysprosium and terbium, which are critical for this material. The material’s adoption could also accelerate the obsolescence of existing electronics, creating a 'magnetic divide' between nations with access to the technology and those without.

Marginalized voices are largely absent from the narrative, despite the DTU-led team including researchers from the Global South. The patent system, which will likely govern this technology, disproportionately benefits wealthy nations and corporations, excluding Indigenous and Southern innovators. The environmental and social costs of rare earth mining—such as the destruction of sacred lands in Congo or the displacement of communities in Inner Mongolia—are also erased. Amplifying these voices could reframe the material as a tool for reparative justice rather than corporate profit.
