Polarization modulation technique for magneto-optical quantitative vector magnetometry
No full textThis letter presents a method for determining the orientation of the magnetization vector during the reversal process in ferromagnetic films using a conventional setup for magneto-optical ellipsometry based on the photoelastic modulation technique for the modulation of polarization. The orientation is obtained through the determination of three orthogonal reduced (i.e., normalized to saturation value) magnetization components as a function of the external field. Test measurements on a reference sample are also presented, which confirm the reliability of the measurements and show what kind of information can be retrieved
Biquadratic exchange coupling in an unequal Fe/Cr/Fe (100) trilayer
No full textWe have investigated the magnetic properties of a (1 0 0)-oriented unequal trilayer, Fe(45 angstroms)/Cr(30 angstroms)/Fe(15 angstroms), by means of Brillouin light scattering and magnetization measurements. The experimental results show that this sample highlights the effect of biquadratic coupling which aligns the magnetization of the Fe layers at 90 °C to each other. We extracted the bilinear and biquadratic coupling strengths by fitting the experimental results with a theory that treats the static and dynamic responses on an equal footing. Our results confirm that the model describes both the static and dynamic properties even when the magnetization of the layers is aligned at 90°. The coupling strengths, and their temperature dependence, are discussed and compared with other results reported in the literature
