Giant magnetoresistance (GMR), tunnelling magnetoresistance (TMR) and spin-transfer torque (STT) MRAM relies on spin polarisation. Furthermore, exchange coupling is also part of the read/write head in storage devices. Heusler alloys are one of the leading candidate materials not only for having high spin polarisation but also their magnetic properties such as high saturation magnetisation and low Gilbert damping which are all essential for developing memory storage devices. To further investigate this material, its magnetic and structural properties must be fully understood. The main goal of this study was to increase the design flexibility for Co-based Heusler spintronic devices by understanding the material's properties.
