“…17 In order to characterize the sensitiveness to TF annealing process, the induced magnetic anisotropy, K u , has been characterized using several procedures. On the one hand, K u can be directly estimated from the value of the anisotropy field, H k , as: On the other hand, the method of Sucksmith and Thompson 18 allows us to obtain the two first coefficients of the magnetic anisotropy K 1u and K 2u based on the relation…”

“…However, the processing required to achieve strain induced anisotropy requires ribbon to be run through a furnace in a reel-to-reel manner. This unconventional annealing method has not been widely adopted commercially but it is an area of active research [17].…”

Fe-based amorphous and nanocrystalline soft magnetic alloys have been intensively researched for many applications, including high efficiency electrical distribution and power conditioning applications. New amorphous foils with a saturation magnetization of 1.63T and new nanocrystalline foils with saturation up to 1.9T have been developed. Often these new materials are not drop-in replacements for the conventional competing alloys and require significant changes in processing to be able to fabricate commercial devices.

“…It is also important that the material be magnetically soft, meaning that hysteresis effects must be small as well. NiZn ferrite is well-known for satisfying both of these properties (Leary et al, 2012) and was therefore used to construct our EDX magnet.…”

We present a novel technique for sorting nonferrous metal scrap by using eddy current separation. However, rather than vary the magnetic field with a spinning rotary drum, our system utilizes a fixed electromagnet excited by an alternating electric current. The technique requires no moving parts other than a feeding mechanism and has the capacity to operate at excitation frequencies up to 50 kHz and beyond. Sorting results are demonstrated using various combinations of metal spheres, which resulted in nearly perfect performance in terms of grade and recovery. We also demonstrate sorting of aluminum alloys from other aluminum alloys, with consistent grade and recovery between 85-95 %.
