EFFECT OF MAGNETIC PROPERTIES ON KERR ROTATION ANGLE IN AMORPHOUS NdTbFeCo ALLOYS

抄録

  Amorphous NdTbFeCo alloys are prepared with different substrate positions and rotation speeds of substrate holder to investigate the effect of magnetic properties on Kerr rotation angle. Angular momentum of the substrate holder induces high squareness of magnetic hysteresis loops in the amorphous alloys. This leads to the fact that the magneto static energy of the hysteresis loops is proportional to remanent Kerr rotation angles.
