Mossbauer spectroscopy of biased magnetic field on cryogenic using a refrigerator

摘要

PURPOSE: A Mossbauer spectrum system capable of applying a magnetic field in an extremely low temperature using a refrigerator is provided to obtain a Mossbauer spectrum by changing the temperature of a sample. CONSTITUTION: A Mossbauer spectrum system capable of applying a magnetic field in an extremely low temperature using a refrigerator comprises a Mossbauer driving unit(100) and a Mossbauer speed transducer(200). The Mossbauer driving unit generates a periodical signal by receiving power supplied from a power unit, and transfers the signal to the Mossbauer speed transducer. The Mossbauer speed transducer has a gamma ray source(300).
