Mossbauer Spectrometer for Measurements in High Magnetic Fields(Part II. Several Instruments and Techniques Developed in HFLSM)
A Mossbauer spectrometer has been designed and constructed for measurements in high magnetic fields beyond 20 T which are generated by a hybrid magnet in the High Field laboratory for Superconducting Materials at Tohoku University. Simple ways were adopted in order to avoid some obstacles for the spectroscopy. The most serious problem was electromagnetic inductions occurring at metallic components in a source drive system. It was found that the replacement of an aluminum drive-rod to a Bakelite one improved remarkably the Mossbauer spectrum. Test measurements of a-Fe at room temperature were satisfactorily performed under the magnetic fields up to 10 T. The results agreed well with the theoretical expectation.
