Mössbauer-Effect Study of Erbium Spin Relaxation in Magnetically Ordered Compounds

Abstract: A-'"D w. WrEDEMAN!o.' J\ (!IlIlIIissiolt fli r Ticjtcmpcratllrjorsc/llmJ;. dcr Baycrischcu A kadem ic dcr l-FissCI'scila/ICIf , ..If unchclI , GUII/awy T he lSolEr hyperfine fields, Er3+ magnetic moments, and electronic spin correlation times in ferromagnetic erbium-al uminum intermetallic structu res have been stud ied between 1.5° and so oK using the Mossbauer effect of the 80.6 keV gamma rays of I"Er. The spin correlation times deduced from both the rale equation model and the Wegener formula follow a… Show more

“…166 Er has an isotopic abundance of 33.41%, and the parent source isotope 166 Ho has a half-life of about 1200 years. Some intermetallic compounds [172][173][174][175] have been studied using this Mo ¨ssbauer spectroscopic isotope.…”

“…8 We have also observed this phenomenon in the Np compounds investigated. At temperatures close to the critical temperature the variation of the hyperfine field in NpAl2 has been analyzed using the conventional formalism to obtain the give rise to a quadrupolar interaction for a transition element ion, even in a cubic crystalline symmetry.…”

“…Estimates of 8 from optical spectra have been generally around 8±1 cm -1 . 3 In particular, Sakatsume and Tsujikawa 4 and Scott and Sturge 5 obtained a value of 8.3 cm -1 . Brumage, Quade, and Lin 6 determined the zero-field splitting to be 8.3±0.2 cm" 1 and g± to be 1.720±0.005 from magnetic susceptibility measurements above 4.2°K.…”
