Unusual Strain glassy phase in Fe doped Ni${}_2$Mn${}_{1.5}$In${}_{0.5}$

Abstract

Fe doped Ni${}_2$Mn${}_{1.5}$In${}_{0.5}$, particularly, Ni${}_2$Mn${}_{1.4}$Fe${}_{0.1}$In${}_{0.5}$, despite having an incommensurate, modulated 7M martensitic structure at room temperature exhibits frequency dependent behavior of storage modulus and loss that obeys Vogel-Fulcher law as well as shows ergodicity breaking between zero field cooled and field cooled strain measurements just above the transition temperature. Both, frequency dependence and ergodicity breaking are characteristics of a strain glassy phase and occur due to presence of strain domains which are large enough to present signatures of long range martensitic order in diffraction but are non interacting with other strain domains due to presence of Fe impurity.
