The substitution of Mn by Ni in (Mn,Fe)2(P,Si) compounds and its magnetocaloric consequences: A comparison with research studies on cobalt regarding tuneable curie temperature, hysteresis and magnetization

With green energy well on its way to becoming a necessity rather than a commodity it is vital to not only focus on improving the source of energy, but also the efficiency of the eventual energy usage. Vapor-compression based household refrigerators are one of the most used electrical appliances in the common household and consume electricity...

Modelling Magnetic Phase Transitions: with Density Functional Theory and the Finite Element Method

The present thesis discusses two modelling endeavours that serve to provide insights into both the magnetic and structural dynamics associated with a first order magnetic phase transition. <br/>Firstly, density functional theory has been used to model the lithiation of a supercell of 2x2x2 the conventional unit cell of the ferromagnet Fe2P....
