“…The weight of the ribbon piece measured was about 1.2 mg. Demagnetization factor of the sample was calculated assuming the size of the ribbon piece measured in SQUID (2 mm × 2 mm × 0.045 mm) to be around 1.5 × 10 −4 , following the model developed for magnetic melt-spun ribbons by D.N. Zhmetko [36]. Corrections for the demagnetization factor were carefully applied before plotting the magnetization results.…”

Rare-earth-free permanent magnets with the L10 phase are actively researched for their potential as a future class of magnetic materials, capable of operating at higher temperatures and in challenging corrosion environments such as renewable energy applications. Among these classes, MnGa shows potential, being cost effective and having interesting magnetic properties. A MnGa magnetic alloy, with composition Mn73.6Ga26.4 in atomic percent, was produced via the out-of-equilibrium method, and its structural and magnetic properties were assessed using X-ray diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and extended magnetic characterization. We show that the MnGa alloy submitted to thermal annealing in optimal conditions exhibits a two-phase microstructure, where small nanocrystals of tetragonal L10/D022 magnetic phase are embedded within a D019 MnGa matrix of a non-collinear antiferromagnetic nature. These co-existing, magnetically different phases produce an optimal set of promising magnetic properties, larger than the values reported in the literature for single-phase MnGa alloys and thin films. Such large values are explained by the exchange coupling between competing non-collinear magnetic sublattices of the D019 MnGa with the net moment of the small magnetic nanocrystals of tetragonal symmetry.

“…In such cases as the measurement of electrical steel strips using an open magnetic circuit or an online yoke type tester with air gaps between the sample and the yokes, the demagnetising field cannot be entirely eliminated. Concerted effort has been dedicated on determination and computation of demagnetising effects [6][7][8][9][10]. The actual magnetic field in the sample can be accurately measured using the Rogowski-Chattock potentiometer or an H-coil.…”

Using basic principles and fundamental equations for calculating the average demagnetising field at the mid-plane of a completely saturated magnetic strip, demagnetising effect was estimated and confirmed by measurements made on various samples. Using the formula, the saturation magnetisation of a group of steel strips, measured using an open magnetic circuit tester, was corrected. The accuracy in determining saturation magnetisation using this method was investigated.
