Magnetic Nanocomposites Enable Smaller Power Components for Computer Chips

University of Florida researchers have developed tiny magnetic devices called stripline microinductors to improve power delivery in computer chips. By utilizing a composite of nickel and iron oxide nanoparticles, the team achieved more than twice the inductance of comparable non-magnetic devices, facilitating smaller voltage regulators.

Shrinking inductors is traditionally difficult because smaller dimensions reduce inductance. This new approach uses electroinfiltration to embed nanoparticles within a metal matrix, creating a material that functions effectively at high frequencies. This advancement allows for more compact hardware capable of supplying steady, controlled voltage to transistors in modern semiconductor manufacturing.
