Ab-initio calculation of magnetic exchange interactions using the spin-spiral method in VASP: Self-consistent versus magnetic force theorem approaches
Umit Dogan Daglum, Maria Stamenova, Ersoy Sasioglu +1
We present an ab initio investigation of magnetic exchange interactions using the spin-spiral method implemented in the VASP code, with a comparative analysis of the self-consisten…
Phonon and magnon jets above the critical current in nanowires with planar domain walls
Maria Stamenova, Plamen Stamenov, Tchavdar Todorov
We show through non-equilibrium non-adiabatic electron-spin-lattice simulations that above a critical current in magnetic atomic wires with a narrow domain wall (DW), a couple of a…
Ab initio comparison of spin-transport properties in MgO-spaced ferrimagnetic tunnel junctions based on MnGa and MnAl
Maria Stamenova, Plamen Stamenov, Nadjib Baadji
We report on first-principles spin-polarised quantum transport calculations (from NEGF+DFT) in MgO-spaced magnetic tunnel junctions (MTJs) based on two different Mn-based Heusler f…
Spin transfer torque in MnGa-based ferrimagnetic tunnel junctions from first principles
Maria Stamenova, Plamen Stamenov, Farzad Mahfouzi +3
We report on first-principles calculations of spin-transfer torque (STT) in epitaxial magnetic tunnel junctions (MTJs) based on ferrimagnetic tetragonal MnGa electrodes, both a…
Multi-scale modelling of current-induced switching in magnetic tunnel junctions using ab initio spin transfer torques
Matthew O. A. Ellis, Maria Stamenova, Stefano Sanvito
There exists a significant challenge in developing efficient magnetic tunnel junctions with low write currents for non-volatile memory devices. With the aim of analysing potential…
Ab initio dynamical exchange interactions in frustrated anti-ferromagnets
Jacopo Simoni, Maria Stamenova, Stefano Sanvito
The ultrafast response to an optical pulse excitation of the spin-spin exchange interaction in transition metal anti-ferromagnets is studied within the framework of the time-depend…
