Reduction of energy cost of magnetization switching in a biaxial nanoparticle by use of internal dynamics
Mohammad H. A. Badarneh, Grzegorz J. Kwiatkowski, Pavel F. Bessarab
A solution to energy-efficient magnetization switching in a nanoparticle with biaxial anisotropy is presented. Optimal control paths minimizing the energy cost of magnetization rev…
Optimal protocol for spin-orbit torque switching of a perpendicular nanomagnet
Sergei M. Vlasov, Grzegorz J. Kwiatkowski, Igor S. Lobanov +2
It is demonstrated by means of the optimal control theory that the energy cost of the spin-orbit torque induced reversal of a nanomagnet with perpendicular anisotropy can be strong…
Optimal control of magnetization reversal in a monodomain particle by means of applied magnetic field
G. J. Kwiatkowski, M. H. A. Badarneh, D. V. Berkov +1
A complete analytical solution to the optimal reversal of a macrospin with easy-axis anisotropy is presented. Optimal control path minimizing the energy cost of the reversal is ide…
Toward room-temperature nanoscale skyrmions in ultrathin films
Anastasiia S. Varentcova, Stephan von Malottki, Maria N. Potkina +3
Breaking the dilemma between small size and room temperature stability is a necessary prerequisite for skyrmion-based information technology. Here we demonstrate by means of rate t…
Effect of anisotropy distribution on local nucleation field in bistable ferromagntic microwires
Grzegorz Kwiatkowski
Critical parameters defining the local nucleation field in amorphous ferromagnetic microwires with positive magnetostriction are obtained analytically through scaling procedures. E…
Domain shape dependence of semiclassical corrections to energy
Grzegorz Kwiatkowski
Stationary solution of one-dimensional Sine-Gordon system is embedded in a multidimensional theory with explicitly finite domain in the added spatial dimensions. Semiclassical corr…
Quantum corrections to phi^4 model solutions and applications to Heisenberg chain dynamics
Grzegorz Kwiatkowski, Sergey Leble
The Heisenberg spin chain is considered in phi^4 model approximation. Quantum corrections to classical solutions of the one-dimensional phi^4 model within the correspondent physics…
Green function diagonal for a class of heat equations
Grzegorz Kwiatkowski, Sergey Leble
A construction of the heat kernel diagonal is considered as element of generalized Zeta function, that, being meromorfic function, its gradient at the origin defines determinant of…
On quantum corrections to dislocations mass
Grzegorz Kwiatkowski, Sergey Leble
Quasi-classical quantization of crystal dislocations field is considered in terms of functional integral. The generalized zeta-function is used to evaluate the functional integral…
