Penn State-led team builds an oxide film that uses chemical disorder to produce magnetic effects
Penn State-led researchers report an oxide thin film whose chemical disorder produces complex magnetic properties, in Advanced Materials. The authors say it could support faster, lower-power electronics and plan to take it to industry.
The Scientist · Science desk
What happened
- The film is itself a high-entropy oxide, a ceramic class introduced in 2015 and pioneered by co-author Jon-Paul Maria, and the team built its own fabrication method to make it.
- The film's layered interfaces came out of work with Oak Ridge National Laboratory in Tennessee that combined materials science and physics.
- The team measured magnetic phenomena at those interfaces and designed experiments to refine the film.
- Almishal called this work and a 2025 Advanced Science paper a first step toward joining magnonics with spintronics.
Why it matters
- constraint Perfecting the film took a decade, and Almishal likened it to crafting a paint and then applying it to a wall. Any partner would have to reproduce that craft before testing devices.
- decision Whether the film moves toward consumer electronics depends on the industry collaboration the team plans. That is where a device-level energy number would first have to appear.
- precedent Almishal is building the college's first magnetics laboratory and calls the work a new direction, so we'd expect follow-up measurements to come from a facility set up for them.
High-entropy oxides stand out for their ability to unite several different elements at the atomic level in a single crystalline structure [8]. This team went after the chemical disorder inside an otherwise perfectly ordered crystal, an intersection the group calls "anomalous crystallinity" [4]. It then used that crystallinity to form layered interfaces and to generate what the researchers describe as a novel phenomenon in magnetism [5].
Lead author Saeed Almishal's case for why that matters is energy. He said the phenomenon assembles disparate atoms to drive magnetic signals, and that magnetic signals require less energy than electrical current to transmit and store data [15]. "We developed this new material with distinct properties that can help engineers refine magnetic functions to drive greater device speeds with less power consumption," Almishal said [11].
The thing this doesn't tell you is the size of the effect. The account of the results does not report a magnitude or a temperature range.
Measuring a phenomenon along interfaces in a film is a materials result. A device needs the effect to survive being built into one, and that is a separate test. The group's new Quantum and Magnetic Materials Measurements Lab is expected to include tools for exploring magnetic properties under varying heat conditions [14]. Temperature behavior is where we would look first.
We'd treat the film as a materials demonstration. Until someone reports a power figure for a working structure, the energy argument is Almishal's general reasoning about magnetism.
What to watch
- A reported magnitude and temperature range for the magnetic effect, ideally against a comparison material.
- First results from the Quantum and Magnetic Materials Measurements Lab, including tests under varying heat.
- An announced industry partner for developing the film toward consumer electronics.
