"high magnetic field strength/ orientation... compositionally graded single-crystal Fe-Co-Ir thin films... Fe magnetic moment increased 1.44-fold and Ir 1.54-fold at 11 at% Ir concentration compared to that at 1 at% Ir concentration... Ir addition increases electron localization/ stronger spin-orbit coupling between 3d electrons of Fe, Co, 5d electrons of Ir, highlighting Ir critical role"
