Theoretical and experimental determination of optical and magneto-optical properties of LuFe2 single crystal

“…In the case of LuFe 2 in which the 4 f states are fully occupied, the theoretical and experimental values of magneto-optical parameters and off-diagonal optical conductivity agree well with each other. 31 But for other RFe 2 and GdCo 2 , where the 4 f states are not fully occupied, the 4 f electrons are actively involved in the magnetic properties and electronic properties of the samples and the LSDA approach did not give good results.…”

Magneto-optic Kerr effect of strongly correlated electron compounds

“…[43] and references therein), or even 4/ compounds in which the localized 4/ bands are far away from the Fermi energy, e.g. LuFe2 [44,45]. For Gd metal the diagonal optical conductivity agrees well with the experimental data of Erskine and Stern [27].…”

“…[49] made some simplifying approximations that led to an energy shift that is proportional to the energy of a band with respect to the Fermi level. The Cr [51], the 3d metals Fe, Co, and Ni [40], PtaMn and Pt3Co [43], and LuFe2 [44,45]. Self-energy corrected spectra showed improved agreement with experiment in all cases.…”

“…The magneto-optic Kerr [44,45]. It was found that the Kerr rotation for polycrystalline GdFe2 is indeed positive for the measured range.…”

Magneto-optic properties of CoFe2−xGaxO4

“…Magneto-optic measurements were performed with a polar configuration setup using a 75 W Xe short-arc lamp light source with a photoelastic modulator ͑PEM͒. 17 In the polar Kerr effect, the near-normal incident, linearly polarized light becomes elliptically polarized light after it is reflected. The major axis of the reflected light is rotated from the polarization axis of the incident light.…”
