Ionic Modulation of Ferromagnetic and Proximity‐Induced Magnetization in Co/Pd Heterostructures Open
Despite the rampant discovery of tunable magnetic properties using magneto‐ionic gating, e.g., magnetic anisotropy, exchange bias, and exchange interactions, there are few studies that give a quantitative understanding of the reversible an…

Large exchange bias enhancement and control of ferromagnetic energy landscape by solid-state hydrogen gating Open
Voltage control of exchange bias is desirable for spintronic device applications, however dynamic modulation of the unidirectional coupling energy in ferromagnet/antiferromagnet bilayers has not yet been achieved. Here we show that by soli…
