Small axial and transverse magnetic field systems for a57Fe M ssbauer study of Kramers systems

A small magnetic field, applied either parallel or perpendicular to the direction of Mossbauer γ-rays, is produced on an absorber by two Mossbauer sample-holders. The sample-holders constitute a convenient and affordable way to obtain the experimental conditions necessary for interpreting the paramagnetic Mossbauer spectra of Kramers iron systems. An application of the two sample-holders is illustrated by the study of a high-spin Fe(III) complex (S = 5/2).
