Abstract

57Fe Mössbauer effect study has been performed on intercalated compound 2H−Fe0.5TaSe2 over a temperature range between 14K and 500K. The highly concentrated intercalation samples 2H−FexTaSe2 with Fe atoms (x up to 2) are prepared by the electrochemical method for the first time. The Mössbauer measurement shows that iron is in Fe3+ high spin state and with the same probability occupies both octahedral and tetrahedral interstices of the Van der Waals gap. The fact that effective masses of iron ions in both sites are close to 57 amu and characteristic temperatures (ΘM =130K, 107K respectively) are found to be relatively small is attributed to the weak forces on Fe3+.
