Magneto-Optical Properties of Materials Containing Divalent Europium

Abstract: A variety of relatively transparent materials containing Eu+ + have become available, thus enabling a study to be made of the magneto-optical properties of the Eu+ + ion in widely different environments. The following materials are reviewed: Eu2SiO4 (orthorhombic structure with a ferromagnetic Curie temperature Tc of 7°K), dilute Eu+ + in CaF2 (fluorite structure), EuF2 (fluorite structure, Tc≈0), EuO−Al2O3−B2O3 glasses (Tc=0), EuSe (NaCl structure, Tc=7°K), and EuO (NaCl structure, Tc=69°K). We… Show more

“…As shown previously for cubic compounds [15,[27][28][29] zero c terms are expected for transitions from a spin-degenerate but orbitally non-degenerate ground state to a spin and orbitally degenerate excited state, in the limit where spin-orbit coupling is zero. Otherwise, c terms for the individual spin-orbit compounds no longer cancel and a pseudo 'a' term proportional to the total spread A t of the spin orbit components and varying as 1/kT is expected.…”

“…Значительно лучше разрешение структуры полос может быть получено по спектрам магнитного кругового и линейного дихроизма и двупреломления. Мак-симумы поглощения проявляют аномальное красное смещение порядка 1000-2000 см' 1 при магнитном упорядочении 10 ' 61 . Столь большая вели-чина смещения говорит о том, что оно связано с возбужденным состоянием, так как обменное расщепление основного 4/-состояния не должно превы-шать -100 см' 1 .…”

“…7,8 The ability of epitaxially integration with Si, 9,10 GaAs 11 and GaN 9 as well as much enhanced Curie temperature via electrons injecting, [12][13][14][15][16][17][18] isostatic pressure, [19][20][21][22] or epitaxial stain, 23,24 makes EuO exceptional and of interest for semiconductor-based spintronics 25 such as spin-filter tunnel barriers. [26][27][28][29] In addition, due to large Faraday 30,31 and Kerr 32 effects derived from the 4f-5d electronic transition and spin configuration of the divalent Eu ions in EuO, considerable attention has been focused on its promising applications in magneto-optic devices. 33,34 Despite of these tremendous observations in the field of linear optics, nonlinear optical properties of EuO, such as sum and difference frequency generation remained unexplored until very recently.…”
