Iridium-doped iron-cobalt (Fe-Co-Ir) alloys, previously identified through machine learning, have been shown to have enhanced magnetic properties, surpassing even the widely used pure Fe-Co alloy.

to the other end consisting of Fe-Co alloy with 11 at% Ir. The team then performed X-ray magnetic circular dichroism (XMCD) measurements on these films, using both soft and hard X-rays.

They utilized high-throughput X-ray magnetic circular dichroism (XMCD) on compositionally graded single-crystal thin films. Asst. Prof. Yamazaki explains, "Unlike previous studies which used ...
