Radial Anisotropy

Co90P10 amorphous microtubes with thickness ranging from 2 to 19 μm were electrodeposited onto Cu wire substrates. Samples exhibit radial magnetic anisotropy as deduced from hysteresis loops and magnetic force microscopy imaging. These microtubes show quite noticeable giant magnetoimpedance effect (GMI) with amplitude depending on layer thickness and frequency. The hysteresis in the GMI curves is small, which can be ascribed to the radial anisotropy. Such small hysteresis is of importance for technological applications.

Standard Software

In the last decade since its development, magnetic force microscopy[l] has emerged as a workhorse in imaging magnetic structures at the sub-micron length scales. It possesses the desirable attributes of robustness, straightforward implementation and a fairly well characterized image contrast formation. In recent years, we have successfully implemented MFM in the presence of a highly controlled external magnetic field.[2] Using this technique, it is possible to follow the sample’s magnetic evolution at various points along it’s magnetization curve. Further, by using standard software implementation, the images can be presented as an animation of the micromagnetic process. We applied this technique to study a variety of slow varying dynamics of magnetic systems, including the dc erasure of thin film recording media[3], the mechanisms of moment rotation and reversal, and the domain wall motion nanostructured magnetic elements[4,5].In this talk, I will review the rudiments of the technique and show the “dynamics” of the magnetization of cobalt and Permalloy alloys interacting with external fields.

ABSTRACTWe demonstrate Magnetic Force Microscopy (MFM) imaging, at room temperature in air, of a 0.25mA DC current path in a 140nm-wide gold nanowire. The nanowire was created by focused ion beam milling of a 12μm wide Cr/Au line of 20nm/110nm Cr/Au thickness. Iterative fitting of the MFM data to an idealized model of the structure yielded a nanowire resistivity a factor of 3.5 higher than that of a control Cr/Au region which was unaffected by the ion beam processing. MFM imaging of an ion-implant patterned line shows current deflection around the implant region.
