Saturated magnetization and glass forming ability of soft magnetic Fe-based metallic glasses

Magnetic Properties in Finemet-Type Soft Magnetic Toroidal Cores Annealed under Radial Stresses

“…It can be seen from Figure 7a that the Ps in all samples increases as the strength of the magnetic field increases, mainly because more immense energy is required for the magnetic core to provide an increase in induction near the saturation [1]. The Ps also increases with increasing frequency in all samples (see Figure 7b), due to eddy current losses at higher frequencies and the dynamic motions of the magnetic domain walls [2]. In the case of stress-annealed samples, the values of Ps at constant frequency (Figure 7a) or constant magnetic field (Figure 7b) have slightly larger amounts than the sample FA.…”

“…Soft magnetic materials are used in various types of electrical devices to store energy and convert or generate electricity [1]. Compared to the conventional soft magnetic materials, nanocrystalline alloys show exceptional magnetic behaviors such as higher saturation magnetic induction, lower coercivity, higher magnetic permeability, and enhanced core loss performance at high frequencies [2][3][4]. These types of alloys pave the way for reaching smaller, lighter, and more efficient electrical components.…”

Machine learning prediction of magnetic properties of Fe-based metallic glasses considering glass forming ability

“…To simplify the theoretical analysis, the theories or models based on condensed matter physics [16,47] usually do not take into account many factors, which could be responsible for the deviation of theoretical predictions of metallic magnetism from experimental results. ML models learn from a large amount of available experimental data and consider many features simultaneously.…”

Graded structure of laser direct manufacturing bulk metallic glass

“…However, the small dimensions of metallic glasses largely hinder their wide applications as structural materials [4,5]. Extending the use of metallic glasses as functional materials could mitigate this problem [6,7]. As a special class of functional materials, functionally graded materials, possess a number of advantages including an improved residual stress distribution, enhanced thermal properties, higher fracture toughness, and reduced stress intensity factors [8].…”
