3 days ago · Based on the depth-dependent magnetization dynamics m (z, t) 𝑚 𝑧 𝑡 m(z,t) italic_m ( italic_z , italic_t ), we now turn to the prediction of the time-dependent complex magneto-optical Kerr response of the magnetic thick film. In general, the complex Kerr response consists of two contributions, the Kerr rotation (real part) and the Kerr ellipticity (imaginary part).
2 days ago · The term “Transit-Time Damping” has been defined variably across different fields of plasma physics. In the context of plasma turbulence, known as the magnetic analogue of Landau damping, transit-time damping describes a process in a time-varying magnetic field where the magnetic mirror force—arising from the parallel gradient of magnetic ...
2 days ago · Abstract: The field of power magnetics plays a crucial role in enabling advancements in electronic power converters. The ninth “Power Magnetics @ High Frequency” workshop returned to its inaugural site in Long Beach, CA, USA, on 24 February 2024, and brought together experts and enthusiasts to discuss the latest developments in magnetic materials, coil design, fabrication techniques, evaluation methods, and modeling tools ( Figure 1).
3 days ago · History Louis Essen (right) and Jack Parry (left) standing next to the world's first caesium-133 atomic clock in 1955, at the National Physical Laboratory in west London.. The Scottish physicist James Clerk Maxwell proposed measuring time with the vibrations of light waves in his 1873 Treatise on Electricity and Magnetism: 'A more universal unit of time might be found by taking the periodic time of vibration of the particular kind of light whose wave length is the unit of length.'
4 days ago · The magnetic field is an abstract entity that describes the influence of magnetic forces in a region. Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position.
