Hydrogen-Driven Perpendicular Magnetic Anisotropy at the Co/Ir Interface

Abstract

Magnetic anisotropy at the nanoscale is a key property for developing advanced spintronic devices, information storage systems, and gas sensors. In this study, we investigate the hydrogen-assisted perpendicular magnetic anisotropy (PMA) in the Co/Ir interface through first-principles density functional theory calculations. Initially, the Co/Ir system exhibits in-plane magnetic anisotropy (IMA). Upon hydrogen absorption, a significant increase in magnetic anisotropy energy is observed, indicating a transition from IMA to PMA. This behavior contrasts sharply with the Co/Rh system, where hydrogen absorption leads to a reduction in magnetic anisotropy energy and a switch from PMA to IMA. The underlying mechanism of these transitions is linked to the hybridization of atomic orbitals at the interface. These findings highlight the potential of hydrogenation as a tool to reversibly control magnetic anisotropy in Co/Ir interfaces, paving the way for new applications in spintronics and gas sensing technologies.

Hidrojen Destekli Dik Manyetik Anizotropi: Co/Ir Arayüzü Örneği

Abstract

Manyetik anizotropi, ileri düzey spintronik aygıtlar, bilgi depolama sistemleri ve gaz sensörlerinin geliştirilmesi için anahtar bir özelliktir. Bu çalışmada, Co/Ir arayüzünde hidrojen destekli dikey manyetik anizotropi (PMA) olgusu, birinci ilke yoğunluk fonksiyonel teorisi (DFT) hesaplamaları kullanılarak incelenmiştir. Başlangıçta, Co/Ir sistemi düzlemsel manyetik anizotropi (IMA) göstermektedir. Ancak hidrojen absorbsiyonunun ardından, manyetik anizotropi enerjisinde belirgin bir artış gözlemlenmiş ve sistemin IMA'dan PMA'ya geçtiği tespit edilmiştir. Bu davranış, hidrojen absorbsiyonunun PMA'dan IMA'ya geçişe neden olduğu Co/Rh sistemi ile zıtlık göstermektedir. Bu geçişlerin altında yatan mekanizma, arayüzdeki atomik orbitallerin hibritleşmesiyle ilişkilidir. Elde edilen bulgular, Co/Ir arayüzlerinde manyetik anizotropinin hidrojen yoluyla geri dönüşümlü şekilde kontrol edilebileceğini göstererek, bu sistemi spintronik ve gaz algılama teknolojilerinde potansiyel olarak kullanılabilir hale getirmektedir.
