520 ▼a Hysteresis is the limiting criterion in many applications of functional materials. Recent understanding and development in shape memory alloys have lead to very low hysteresis materials. Low hysteresis shape memory alloys with unusual magnetoele
520 ▼a In this thesis, we try to understand magnetic hysteresis in cubic ferromagnets using the framework of micromagnetics. We look at two cubic materials: Galfenol (Fe74Ga26 and Fe83Ga17) and Permalloy (Fe21.5Ni78.5). The material parameters of Galfe
520 ▼a We also touch upon the well known Permalloy problem in this thesis. Permalloy has very low coercivity at a puzzling material composition. We make few interesting observations about the magnetic microstructure of the Permalloy.
520 ▼a Finally, we shall report the results of some novel experiments that were aimed to synthesize an elusive hard ferromagnet known as Tetrataenite.
