It is shown that in the employed Voigt geometry the magnetic linear birefringence and the dichroism reach values 10<sup>-4</sup>, and have a strong dependence on the wavelength and a strong anisotropy. The absorption spectra were obtained at temperatures of 30 K, 82 K, 100 K using magnetic field up to 25 kOe applied parallel and perpendicular to the electric vector E linearly polarized light on the <sup>7</sup>F<sub>6</sub>-<sup>7</sup>F<sub>0</sub> and <sup>7</sup>F<sub>6</sub>-<sup>7</sup>F<sub>1</sub> optical transitions region. The aim of this research was revealing of a role of contributions of exchange interaction and a crystal field in splitting of energy levels of the basic condition <sup>7</sup>F<sub>6</sub> ion Tb<sup>3+</sup> multiplet in Tb ferrite-garnet by studying of character of spectra of magnetic linear dichroism (MLD) paramagnetic and ferrimagnetic crystals placed in an external magnetic field. Moreover, the assumption about nonreciprocity of magnetic linear birefringence (MLB) spectra and dichroism with the change of the relative orientation of the magnetization vector I and the light wave vector has been experimentally confirmed. This effect may be used as a base for the design of the different transducers, for example, magnetooptical optical channels commutator.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>crystal field interactions; exchange interactions (electron); garnets; light polarisation; magnetic anisotropy; magnetic circular dichroism; magnetisation; paramagnetic materials; terbium compounds; visible spectra; Tb<sub>3</sub>Fe<sub>5</sub>O<sub>12</sub>; Tb<sub>3</sub>Ga<sub>5</sub>O<sub>12</sub>; absorption spectra; anisotropy; crystal field; electric vector; energy level splitting; exchange interaction; ferrimagnetic crystals; light polarization; magnetic linear birefringence spectra; magnetic linear dichroism; magnetization vector; magnetooptical optical channels commutator; magnetooptical properties; optical transitions; optical transitions region; paramagnetic crystals; temperature 30 K to 100 K; terbium gallium garnets; terbium iron garnets; transducers; Absorption; Anisotropic magnetoresistance; Crystals; Garnets; Iron; Perpendicular magnetic anisotropy; Magnetic linear birefringence; magnetooptical transducers;</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>fLanguage : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>English</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Journal_Title : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>Magnetics, IEEE Transactions on</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Publisher : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>ieee</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>ISSN : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>0018-9464</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Type : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>jour</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>DOI : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>10.1109/TMAG.2013.2273660</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Filename : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>6692932</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Link To Document : </div><div class='valueDiv leftDirection leftAlign fullRecValueEnglish col-xs-8 col-sm-10'><a href='https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=38211' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=38211</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=$
