Abstract

An attempt was made to obtain excellent corrosion resistant magneto-optical films with good magneto-optical properties by adding Cr to TbFeCo films at levels of more than 5 at%. Addition of Cr causes preferential decrease in sublattice magnetization of transition metals in rare-earth-transition metal amorphous alloys. As a result, Tb19Fe45Co29Cr7 film was found to have high corrosion resistance with good Kerr rotation of 0.3° and also a high readout carrier to noise ratio (CNR) of 51 dB.
