Abstract By inserting a non-magnetic Cu layer between permalloy (NiFe) and polycrystalline iridium manganese (IrMn) thin films with (111) mixture of (002) textures, the dependence exchange bias, coercive field magnetic reversal mechanism on spacer thickness has been investigated both experimentally by micromagnetic simulation technique in temperature range 10-300 K. Magnetic force microscopy measurements display surface domain structure random orientations texture regions uniform textured...
Manipulation of antiferromagnetic sublattice orientations, a key challenge in spintronic device applications, requires unconventional methods such as current induced torques including Spin Transfer Torque (STT) and Spin-Orbit (SOT). In order to observe the deviation Néel vector from anisotropy axis, one simplest approaches is electrical detection, whereby monitors change resistance function applied current. this work, we have investigated conditions under which an ultra-thin metallic...
Nonvolatile spintronics-based devices that utilize electron spin both to store and transport information face a great challenge when scaled nano dimensions due loss of thermal stability stray field induced disturbance in closely packed magnetic bits. The potential replacement ferromagnetic materials with antiferromagnets may overcome some these issues owing the superior robustness sublattice orientations as long theyare kept well below N\'eel temperature, which is hard measure conventional...
Abstract We prepared Pt/Co/Pt( t Pt )/IrMn heterostructures with perpendicular exchange bias (PEB) by inserting a spacer between Co and IrMn. X-ray diffraction demonstrates that the IrMn layers exhibit (111) texture promoting PEB. Here, samples for various thicknesses double-shifted hysteresis loops coexistence of positive negative biases (EBs). Magnetic force microscopy measurement indicates this behavior in as-grown state results from formation an antiferromagnetic bidomain opposite signs....
Bu çalışmada, Si(100)/SiO2(~200 nm) alttaş üzerine 4 - 20 nm arasında değişen kalınlıklarda büyütülen permalloy ince filmlerin yapısal ve manyetik özellikleri araştırılmıştır. Permalloy filmler eğik açılı magnetron saçtırma tekniği kullanılarak yüksek vakumlu odada hazırlandı. X-ışını foto-elektron spektroskopisi ölçüm sonuçlarından, permalloyun alaşım komposizyonu oranı %21 Fe %79 Ni olarak bulundu. kırınım yansıma ölçümleri, filmlerinin (111) yönünde, düşük yüzey pürüzlülüğüne sahip...
