The film is thinner than a human hair and built from layered interfaces within the HEO structure, a result of over a decade of research and a fabrication method that creates this specific thin-film material.

The material is an advanced high-entropy oxide (HEO) thin film, developed from more than ten years of work following the 2015 emergence of HEOs, and fabricated to form layered interfaces that drive a new magnetism phenomenon.

Funding for the project came from NSF and other federal sources, including the Penn State MRSEC, with additional support from the Spallation Neutron Source at Oak Ridge National Laboratory.

Funding support comes from NSF, Penn State MRSEC, and related federal sources; the work is positioned within Penn State’s Quantum and Magnetic Materials Measurements Lab and the Almishal Group in the Materials Research Institute.

The research is positioned as a step toward practical applications in consumer electronics and large-scale data centers, potentially offering 10 to 100 times greater efficiency in data centers through magnetic-based mechanisms.

The work focuses on anomalous crystallinity—a form of chemical disorder within ordered crystal structures—to generate magnetic signals that require less electrical current to transmit and store data.

The team explored anomalous crystallinity—chemical disorder within an ordered crystal structure—to create interfaces that assemble disparate atoms to enhance magnetic signals, reducing energy required for data transmission and storage.

A multination collaboration led by Penn State researchers has developed a novel ultra-thin film made from high-entropy oxides (HEOs) with complex magnetic properties that could enable faster, more energy-efficient electronics and greater data storage.

The research, published in Advanced Materials, builds on a 2025 Advanced Science paper and aims to integrate magnonics and spintronics with traditional electronics for future devices and data centers.

A dedicated magnetics laboratory and the Quantum and Magnetic Materials Measurements Lab at Penn State will enable broader testing of magnetic properties under varying temperatures, with plans to partner with industry for further development.

The team collaborated with Oak Ridge National Laboratory and expanded from foundational HEO work introduced in 2015, with findings published in Advanced Materials and related 2025 work in Advanced Science.

The team plans industry collaborations to advance the film toward everyday consumer electronics, with potential efficiency gains in data centers projected at 10 to 100 times, primarily due to magnetism-enabled reductions in electrical current requirements.
