WebOct 1, 2024 · In this Letter, we demonstrate that spin valve systems consisting of a magnetically soft free Fe layer and a magnetically hard Fe fixed layer pinned by an antiferromagnetic Ir 23 Mn 77 layer, which are separated by a Pt or W spacer, are efficient switchable spintronic terahertz (THz) emitters. WebDec 26, 2024 · The insertion of an ultra-thin IrMn(0.8–1.2 nm) layer at the CoFe interface improved the CoFe hysteresis, i.e. the ratio of exchange bias field (H ex) to coercivity (H c) was increased. The effects associated with thin b-PtMn, i-PtMn, and IrMn/i-PtMn layers were presumably due to a mismatch between lattice constant and a/c ratio of the PtCr.
WebHere, using time-resolved terahertz emission spectroscopy, we construct a spintronic terahertz emitter consisting of an IrMn 3/Ni−Fe heterojunction. A femtosecond spin current pulse is generated in the thin film of the Ni−Fe layer when it absorbs a femtosecond laser pulse, and then the spin current is converted into a transient charge ...
