Investigation of the magneto-optical properties in transparent region of implanted (YBiCa)3(FeGe)5O12 garnet films

Abstract

We investigated equatirial Kerr effect in transparent region ħω=0.5–2.3 eV of the ion-implanted (YBiCa)3(FeGe)5O12 ferrite-garnet films. The implantation process was carried out at the room temperature by Ne+ ions with energy of 100 KeV and with various doses (0.5–2.5) ·1014 ion/cm2. We discovered that slight deviation of the plane of external alternating magnetic field from plane of sample leads to appearance intensive magneto-optical maximum in transparent region of garnet films ħω =0.5–2.3 eV. In the proceeding, we have also found that the deviation of polarization plane from P-component of incident light leads to the appearance of the similar magneto-optical effects in this region. The research of magnetization processes in transparent region of garnet films showed that the formation of magneto-optical effects in region ħω =0.5–2.3 eV has a rather complex character.
