Abstract We report a systematic study of structural properties and quasi-static and dynamical magnetization behavior of trilayered systems produced in the meander-line geometry. Our samples consist of NiFe/Cr/NiFe layers produced by the magnetron sputtering technique. Here we grow samples with NiFe and Cr layers in a wide thickness range, keeping constant the total thickness of the trilayer. The structural properties and the quasi-static magnetic behavior were characterized by X-ray diffraction and magnetization curves, respectively. The magnetization dynamics was investigated through the magnetoimpedance effect at the high-frequency regime. The sample geometry, as well as the configuration of the magnetic fields, employed in the magnetoimpedance measurements, enabled us to modify the frequency limits in which the distinct mechanisms are acting on the magnetoimpedance response. Hence, we are able to modify/tailor the impedance as a function of both the magnetic field and probe frequency. Our results pave the way for the exploration the meander-line geometry at the high-frequency regime in samples with low dimensionalities.

曲折线三层薄膜中的高频磁阻抗效应

摘要 我们报告了对折线几何中产生的三层系统的结构特性和准静态和动态磁化行为的系统研究。我们的样品由磁控溅射技术生产的 NiFe/Cr/NiFe 层组成。在这里，我们在很宽的厚度范围内生长具有 NiFe 和 Cr 层的样品，保持三层的总厚度不变。分别通过X射线衍射和磁化曲线表征了结构特性和准静态磁行为。通过高频区域的磁阻抗效应研究了磁化动力学。用于磁阻抗测量的样品几何形状以及磁场的配置，使我们能够修改不同机制作用于磁阻抗响应的频率限制。因此，我们能够根据磁场和探头频率来修改/定制阻抗。我们的结果为探索低维样本中高频区域的曲折线几何形状铺平了道路。
