00925njm 22002777a 4500 dc Nieves Cordones, Pablo author Arapan, Sergiu author Schrefl, T. author Cuesta López, Santiago author 2017-12 In this work we develop an atomistic spin dynamics model for the ideal Mn 50 Al 50 τ -phase by means of first-principles calculations. The model is applied to study the domain wall and antiphase boundary phenomenology. In particular, it allows us to obtain the dependence on the interfacial exchange coupling of the nucleation and depinning fields, as well as the macroscopic magnetization profile across the antiphase boundary. We find that microscopic antiferromagnetic exchange coupling stronger than 10 meV could unavoidably lead to the formation of a domain wall at the antiphase boundary. 2469-9950 http://hdl.handle.net/10259/5712 10.1103/PhysRevB.96.224411 2469-9969 Atomistic spin dynamics simulations of the MnAl τ-phase and its antiphase boundary
