| dc.description | Non-linear susceptibility (χ<sub>nl</sub>) measurements on MgAl<sub>1.4</sub>Fe<sub>0.6</sub>O<sub>4</sub> show spin-glass ordering in a cubic spinel ferrite, for the first time. The ordering gives a peak in the temperature dependence of χ<sub>nl</sub>, which shows that the spin ordering is a cooperative phase transition. The values of the critical exponents, obtained from χ<sub>nl</sub> as the temperature approaches the transition temperature, are found to lie in the range obtained from measurements on other spin glasses. We also investigate the static and dynamical effects of the spin-glass ordering on Mössbauer spectra. Dynamical spin freezing as a result of spin-glass ordering is observable in Mössbauer spectra. |
