Structural and magnetic properties of a Ni50 Mn34.8 In15.2 ferromagnetic shape memory alloy doped by F 57 e at the Mn sites have been studied by x-ray diffraction, Mössbauer spectroscopy and superconducting quantum interference device magnetometry. Obtained experimental results have disclosed unique magnetostructural transition from a high-temperature ferromagnetic austenitic phase to a low-temperature paramagnetic martensitic phase at Mf =290 K. Complex magnetic ordering which can be classified as a cluster glass state is formed in Ni50 Mn34.3 F 57 e0.5 In15.2 on further cooling below TCM =162 K. The abnormal magnetostructural transition observed in Ni50 Mn34.3 F 57 e0.5 In15.2 is suggested to originate from the weakening of exchange interactions due to an abrupt change in Mn-Mn interatomic distances occurring upon the martensitic transformation.
