Carbon-Doped CoMnSi Heusler Alloy Microwires with Improved Thermal Characteristics of Magnetization for Multifunctional Applications.

In the current work, we illustrate the effect of adding a small amount of carbon to very common CoMnSi Heusler alloy-based glass-coated microwires. A significant change in the magnetic and structure structural properties was observed for the new alloy CoMnSiC compared to the CoMnSi alloy. Magneto-structural investigations were performed to clarify the main physical parameters, i.

Enhancing the Squareness and Bi-Phase Magnetic Switching of CoFeSi Microwires for Sensing Application.

In the current study we have obtained CoFeSi glass-coated microwires with different geometrical aspect ratios, = d/D (diameter of metallic nucleus, d and total diameter, D). The structure and magnetic properties are investigated at a wide range of temperatures. XRD analysis illustrates a notable change in the microstructure by increasing the aspect ratio of CoFeSi-glass-coated microwires.

Ni-Mn-Sn-Cu Alloys after Thermal Cycling: Thermal and Magnetic Response.

Heusler Ni-Mn-Sn-based alloys are good candidates for magnetic refrigeration. This application is based on cycling processes. In this work, thermal cycles (100) have been performed in three ribbons produced by melt-spinning to check the thermal stability and the magnetic response.
