Superexchange dominates in magnetic topological insulators
Cezary Sliwa, Carmine Autieri, Jacek A. Majewski +1
It has been suggested that the enlarged spin susceptibility in topological insulators, described by Van Vleck's formalism, accounts for the ferromagnetism of bismuth-antimony topol…
Ab initio theory of graphene-iron(II) phthalocyanine hybrid systems as scalable molecular spintronics
Marcin Zemła, Kamil Czelej, Jacek Majewski
Graphene - transition metal phthalocyanine (G-MPc) hybrid systems constitute promising platforms for densely-packed single-molecule magnets (SMMs). Here, we selected iron(II) phtha…
Ordering effects in 2D hexagonal systems of binary and ternary BCN alloys
Agnieszka Jamróz, Jacek A. Majewski
We present theoretical study of ordering phenomena in binary , and ternary alloys forming two-dimensional, graphene-like systems.…
Functionalization of carbon nanotubes with -CHn, -NHn fragments, -COOH and -OH groups
Karolina Z. Milowska, Jacek A. Majewski
We present results of extensive theoretical studies concerning stability, morphology, and band structure of single wall carbon nanotubes (CNTs) covalently functionalized by -CHn(fo…
Theory of Spin Transport Across Domain-Walls in (Ga,Mn)As
Rafal Oszwaldowski, Jacek A. Majewski, Tomasz Dietl
We present results of numerical calculations of domain-wall resistance in the ferromagnetic semiconductor (Ga,Mn)As. We employ Landauer-Buttiker formalism and the tight binding met…
Influence of band structure effects on domain-wall resistance in diluted ferromagnetic semiconductors
R. Oszwałdowski, J. A. Majewski, T. Dietl
Intrinsic domain-wall resistance (DWR) in (Ga,Mn)As is studied theoretically and compared to experimental results. The recently developed model of spin transport in diluted ferroma…
