摘要

Abstract

BSTRACTThe heterointerfacing of different materials with competing magnetic orders forms the basis for today’s spintronic devices

however materials compatibility has remained a major limitation to the conception of new multilayered systems. Here

we uncover a multilayer of competing magnetic orders within a single layer of FeRh after low-energy He-ion irradiation: metamagnetic

ferromagnetic

and spin glass. Polarized neutron reflectometry

irradiation modeling

and density functional theory calculations reveal a direct correlation between the disorder concentration

the depth-dependent magnetic ordering

and the onset of the metamagnetic transition. Such a heterostructure opens the door to new paradigms in antiferromagnetic electronics and ultra-low-power magnetization controllability.
