A research team led by Professor Jung-Il Hong of the Department of Physics and Chemistry at DGIST has successfully used current pulses to alter the spin configuration within a ferrimagnetic material, lowering its "compensation temperature"—the temperature at which opposing magnetizations cancel each other out—by up to approximately 110 K.
The research is published in the journal Advanced Functional Materials.
The team controlled the material's magnetic properties using only electrical signals, without changing the composition or thickness of the alloy. The technology could have applications in next-generation spintronic memory devices.
