Thermal Design of High Performance Magneto-Optical Data Storage Films

Magneto-optical properties of MnBiAl thin films

High-density optical data storage

Since the introduction of optical data storage systems in the 1970s, we have observed a stepwise increase in their storage capacity using the same means for resolution improvement as in classical microscopy and optical lithography, namely, a reduction in the source wavelength and an increase in the numerical aperture of the imaging optics. In this paper we briefly address the historical develop...

Large area magneto-optical investigations of YBCO thin films

A new apparatus for magneto-optical investigations of high temperature superconducting ~HTS! films as large as 20320 cm is presented. With this equipment flux penetration of an external magnetic field into YBCO thin films has been studied by scanning the samples through an inhomogeneous magnetic field ~magneto-optical scanning technique, MOST!. The normal penetration of magnetic flux into a sup...

MAGNETO-OPTICAL KERR EFFECTS OF AMORPHOUS Nd-Co FILMS

The complex off-diagonal components of conductivity tensor (g:, = 4, + i<,) of Co, a-Nd-Co and a-Y-Co was obtained by measuring magneto-optical Kerr effects, reflectivity and transmissivity in the range of fw = 0.8 eV 5eV. Nd-Co showed much greater wcr;, than Y-Co and the difference was deduced to be due to 4f T--t 5d 1. electron transition of Nd.
