Influences of magnetic field in viscoelastic fluid

This communication influences on magnetohydrodynamic flow of viscoelastic fluid with magnetic field induced by oscillating plate. General solutions have been found out for velocity and shear stress profiles using mathematical transformations (Integral transforms). The governing partial differential equations have been solved analytically under boundary conditions u(0,t)=A_0 H(t)sinΩt and u(0,t)...

Optical Gyrotropy and Birefringence in Magnetic Crystals

Role of magnetic circular dichroism in all-optical magnetic recording.

Using magneto-optical microscopy in combination with ellipsometry measurements, we show that all-optical switching with polarized femtosecond laser pulses in ferrimagnetic GdFeCo is subjected to a threshold fluence absorbed in the magnetic layer, independent of either the excitation wavelength or the polarization of the laser pulse. Furthermore, we present a quantitative explanation of the inte...

Vacuum Birefringence in a Rotating Magnetic Field

We calculate the vacuum polarization-induced ellipticity acquired by a linearly polarized laser beam of angular frequency ω̄ on traversing a region containing a transverse magnetic field rotating with a small angular velocity Ω around the beam axis. The transmitted beam contains the fundamental frequency ω̄ and weak sidebands of frequency ω̄±2Ω, but no other sidebands. To first order in small quan...
