Kurzfassung:
Nowadays antiferromagnets compete with ferromagnetic materials in the fields of active
spintronics devices. Antiferromagnets are faster, higher protected from noise and more
scalable than their ferromagnetic counterparts. However, their magnetic dynamics differs
form the magnetic dynamics of ferromagnets and in many cases seems contrintuitive to
"ferromagnetic community". In my lecture I will highlight the peculiarities of
antiferromagnetic dynamics in the presence of spin currents (spintronics), spin-orbit
torques (spinorbitronics) and temperature gradients (caloritronics). I will also give and
discuss several examples which illustrate differences and similarities of antiferro- and
ferromagnetic spin-smth-tronics.
Kurzbiographie:
Graduated from Moscow Institute of Physics and Technology in 1985. After working for
10 years in the National Academy of Science of Ukraine (Institute for Metal Physics)
jointed National Technical University "KPI" for the pilot project aimed at starting
the physical-technical education in Ukraine. Since 2000 developed and taught the course
of "Quantum information theory" for Bachelor and Master students (for the first time in
Ukraine). Since 2015 joined Sinova group at the Johannes Gutenberg-Universität.
Scientific interests: theory of magnetism and, in particular, antiferromagnetism,
antiferromagnetic spintronics, quantum optics.
