Abstract
A pulsed magnetic field (MF) up to 0.6 T leads to the generation of fine microstructure through the change in the dynamics of the interaction process between the MF and the magnetic- and microstructure in Co49Ni21Ga30 magnetic shape memory alloy single crystals. This paper addresses the impact of pulsed and permanent MF on the transformation behaviour in Co49Ni21Ga30. A pulsed MF can result in different microstructural accommodation processes in stress-induced martensite, as compared to an application of a mechanical stress or permanent MF. In a pulsed MF, the development of new nano-twin systems in the martensitic structure of the CoNiGa alloy and the formation of fine magnetic domains at the microscale are observed.
