Ferromagnetic Materials

Technique for imaging magnetization dynamics developed in a joint project

Nanosized magnetic particles called skyrmions are considered highly promising candidates for new data storage and information technologies

"Inverse spin Hall effect" works in several organic semiconductors

Brookhaven Lab and Stony Brook University researchers measure the quantum fluctuations behind a novel magnetic material's ultra-cold ferromagnetic phase transition.

Brookhaven Lab scientists find surprising locked charge polarizations that impede performance in next-gen materials that could otherwise revolutionize data-driven devices.

Ferroelectric materials–substances in which there is a slight and reversible shift of positive and negative charges–have surfaces that are coated with electrical charges like roads covered in snow.  Accumulations can obscure lane markings, making everyone unsure which direction traffic ought to flow; in the case of ferroelectrics, these accumulations are other charges that “screen” the true polarization of different regions of the material.

Mechanism may provide route for using multiferroic materials in RAM.

A magnetic phenomenon newly discovered by MIT researchers could lead to much faster, denser and more energy-efficient chips for memory and computation.
