Abstract
The structure,hyperfine interactionsandmagneticpropertiesoftheseriesofmultiferroicBim+1Ti3Fem−3 O3m+3 Aurivilliuscompoundswith m¼4–8 werestudiedusingX-raydiffraction, 57Fe Mössbauer spectroscopyandvibratingsamplemagnetometry.Sampleswerepreparedbytheconventionalsolid- state sinteringmethod.Bulkmagneticmeasurementsshowedthatfor m¼4 thecompoundis paramagnetic downto2Kwhileinthecompoundwith m¼5 theantiferromagnetictypetransition wasobservedat11K.Inthecaseofcompoundswith m¼6–8 muchmorecomplexmagneticbehavior wasfound.Forthesecompoundsagradualspinfreezingandantiferromagneticspinglass-likeordering wereobservedondecreasingtemperature.Thetemperatureofspinglassfreezingwasdeterminedas 260, 280and350Kfor m¼6, 7and8,respectively.Room-temperatureMössbauerspectraofallthe compounds studiedconfirm theirparamagneticstate.However,liquidnitrogenandliquidhelium temperaturemeasurementsrevealmagneticorderingwitharesidualparamagneticphasecontribution for thecompoundswith m¼5–8.
