Microwave generation in ferromagnetic nonlinear pulse forming lines (NPFLs) depends strongly on material properties, particularly the damped gyromagnetic precession of a ferrite’s magnetic moments. Additionally, temperature-dependent material properties, such as saturation magnetization and coercivity, are critical for assuring stable operation due to their influence on the output center frequency. In this study, we measured the […]

Effects of Nb Content on the Microstructure and Magnetic Properties of the Sm₁.₂Zr₀.₂(Fe₀.₈Co₀.₂)₁₁.₅-ₓ Ti₀.₅Nbₓ (x=0 –0.4, at.%) Alloys

ThMn12-type SmFe12-based magnet is suggested to be a promising permanent magnet because of its intrinsic magnetic properties and thermal stability. However, their potential applications are currently limited, as the existence of a soft magnetic α -Fe phase in the alloy deteriorates the hard magnetic properties. Hence, in this work, Nb element was introduced into the […]

Effect of Manufacturing Influences on Magnetic Performance Parameters of Sub-Fractional Horsepower Motors

October 1, 2021Stefan Leitner, Hannes Gruebler and Annette MuetzeJournalForging, Lamination, Laser beam cutting, Magnetic hysteresis, Permanent magnet motors, Torque, Torque measurement

Depending on the stator lamination manufacturing processes (e.g., punching, laser cutting, clamping, welding, interlocking, and bonding), the motor’s magnetic performance parameters, such as cogging torque, hysteresis torque, and iron losses, can vary significantly. In sub-fractional horsepower (SFHP) permanent magnet motors, the manufacturing influence is typically even more severe because, due to their small dimensions, practically, […]

Spin Hall magnetoresistance and spin orbit torque efficiency in Pt/FeCoB bilayers

May 1, 2021Alessandro Magni, Vittorio Basso, Alessandro Sola, Gabriel Soares, Nicola Meggiato, Michaela Kuepferling, Witold Skowroński, Stanisław Łazarski, Krzysztof Grochot, Mehran Vafaee Khanjani, Juergen Langer, Berthold OckerEarly AccessMagnetic anisotropy, Magnetic domain walls, Magnetic domains, Magnetic hysteresis, Magnetization, Magnetomechanical effects, Perpendicular magnetic anisotropy

The spin Hall magnetoresistance (SMR) of Pt/FeCoB bilayers with in-plane magnetocrystalline anisotropy was analysed with respect to a second order effect in the sensing current which acts, through the spin Hall effect in Pt, as a torque on the magnetization of the ferromagnetic layer and changes slightly its configuration. This leads to a small current […]
