First Order

A first-order metamagnetic transition from antiferromagnetic to ferromagnetic state in La (Fe0.88Al0.12-xSix) compounds was investigated using Mossbauer effect. The exchange-related clusters in the ferromagnetic and antiferromagnetic state are shown to exist. The influence of Si on magnetic structure is observed.

Mössbauer Study

AbstractThe behaviour of iron in the natural weathering of hornblende in a sedentary soil profile has been investigated using the Mòssbauer effect. The spectra from samples at different stages of weathering show appreciable differences which can be accounted for if ferrous iron is lost preferentially from M(3) sites where it is coordinated to hydroxyl groups in a trans arrangement. Unlike biotite the proportion of ferric iron does not increase during weathering and this illustrates the difficulty with which the ferrous iron is oxidized in the amphibole structure.

Mössbauer Study

ABSTRACTMössbauer effect measurements have been taken of iron and tin introduced into brown coal to act as catalysts for hydrogenation. Spectra taken with 119Sn show that after introduction from solution, the tin appears as SnO2. During subsequent hydrogenation in an autoclave, some of the SnO2 is converted to β-tin and SnS. Ion-exchanged iron is shown from 57Fe measurements to occupy at least one site not populated in the native coal. Line broadening in this site and the other two original sites indicate the existence of variations in the local environment.
