Exploratory synthesis and characterization of Mn-based chiral nanomagnets, thin films and multilayers

POSTER

Abstract

Chirality refers to single handedness in physical properties of materials that lack mirror symmetry in their crystal structure. Mn-ions are known dopants for the optical chiral property development in nanomaterials, organic-inorganic hybrids and thin films [1, 2]. Additionally, bulk Mn-based materials such as MnSi[3] and Mn3X (Sn, Ge)[4] also exhibit chiral magnetism. Chiral nanomagnets and heterostructures are promising platforms for chiral magneto-optical applications which are greatly limited by low Curie temperatures. We will review the status of Mn-based chiral magnetic materials in bulk, nanomaterials and thin films and present an exploratory electrochemical synthesis[5] and characterization report of high Curie temperature Mn based magnetic nanomaterials materials and thin films.
