Magnetoresistive Fe19Ni81/Tb-Co medium with an internal magnetic bias

Optimization of Functional Parameters of Magnetoresistive Fe₂₀Ni₈₀/Fe₅₀Mn₅₀/Fe₂₀Ni₈₀ Films

“…Prototypes of sensor had topology of the electric bridge with four arms containing inclined (45°) film meanders [6]. Appearance of the separate chip as part of the wafer is shown in Fig.…”

Influence of the Interface Quality on Magnetic Properties of Fe20Ni80/Tb-Co Films with Unidirectional Anisotropy

“…Fig. 1a) [6]. Also it is possible to obtain hysteresis loop of the permalloy layer if magnetic eld range does not exceed coercivity of the ferrimagnetic layer.…”

“…Mechanism of the magnetic coupling often remains obscure because of complexity of magnetic frustrations and compositional gradients in the interface region [3,4]. Introduction of magnetic or nonmagnetic spacers [5] as well as heat treatments [6] were demonstrated to be an effective way of modication of magnetic and magnetoresistive properties of sandwiches or multilayers. In this study we considered eect of annealing and introduction of ultrathin Ti spacer on magnetic properties of exchange coupled sandwiches based on amorphous ferrimagnetic Tb 26 Co 74 and soft magnetic Fe 20 Ni 80 layers with unidirectional anisotropy.…”

Influence of Temperature on Magnetic Properties of Tb26Co74/Co/Fe20Ni80Films with Exchange Bias

“…Interlayer region can be modied articially by introduction of the ultrathin nonmagnetic spacer [4] or by selective annealing of the seed permalloy layer [5]. This paper is devoted to the study of inuence of temperature on unidirectional anisotropy in exchange coupled sandwiches based on According to data of X-ray diraction analysis Fe 20 Ni 80 layer was nanocrystalline, Tb 26 Co 74 layer in amorphous condition.…”

“…Thin lms consisting of exchange coupled Fe 20 Ni 80 and TbCo layers are of substantial fundamental and applied interest [16]. Due to the proper combination of magnetic and magnetoresistive properties such lms have been used in magnetic sensors [5].…”
