“…The microscopic origin of this effect remains unclear; however, some reports describe the phenomenology behind this effect by considering the domain state model [2], the role of the interfacial spins [3], and roughness of the ferromagnet-antiferromagnet interface [4]. On the other hand, materials exhibiting this effect found technological application in sensors [5,6], magnetic read heads [7], spintronic devices [8][9][10], or as shape memory alloys [11].…”

Materials exhibiting an exchange bias eﬀect are a class of magnetic systems that have a wide range of possible technological applications e.g. in sensors, read heads, and spintronic devices. In this study, we demonstrate the eﬀect of laser interference patterning on the magnetic properties of Pd/CoO/Co/Pd multilayers. Laser patterning creates arrays of well-ordered stripes, rectangles, and squares on the substrate surface. We found that the laser treatment caused magnetic softening of the structure edges while the centers of the objects remained unchanged and exhibited the exchange bias eﬀect. In this study we focused on the shape and conﬁgurational magnetic anisotropies induced by patterning and showed that the magnetic properties varied depending on the angle at which the external magnetic ﬁeld was applied with respect to the pattern geometry.

“…For these alloys, during the martensitic transformation, it will undergo a magneto‐structural transition from ferromagnetic austenite phase to weak‐magnetic martensite phase. Thus, magnetic properties such as magnetic shape memory effect, magneto‐caloric effect, exchange bias effect, and magneto‐resistance effect, can be realized during the martensitic transformation.…”

Microstructural and Crystallographic Insights in a Martensite/Austenite Dual Phase Ni–Mn–Sb Alloy

For Ni-Mn-Sb multifunctional alloy, its microstructure and crystallographic information are decisive factors for its multiple magnetic field induced properties, such as magnetic field induced shape memory effect, magneto-caloric effect, exchange bias effect, and so on. While, studies on such field are rarely conducted. In the present work, a comprehensive study on microstructural features and crystallographic characteristics has been conducted in a martensite/austenite dual phase coexisting polycrystalline Ni 50 Mn 37 Sb 13 alloy. Results show that the martensite is self-organized in plates in the original austenite. The intra-plate martensite presents a fine lamellar microstructure and each fine lamella corresponds to one martensite variant. Crystallographic orientation analysis indicates that each martensite plate exists four differently oriented martensite variants and they can form three types of twins, type I, type II, and compound twin. Trace analysis results show that the interface between adjacent variants are their twinning plane K 1 . Further investigation on martensitic transformation orientation relationship reveals that the Pitsch orientation relationship, specified as 0 1 1g A È // 2 2 1g M È and < 0 11> A //< 1 22> M , is the effective one from austenite to martensite. All the above results offer basic microstructural and crystallographic information on Ni-Mn-Sb alloys and can be useful for further investigation on property optimization of these alloys.
