Surface contribution to the anisotropy of magnetic nanoparticles
D. A. Garanin, H. Kachkachi
We calculate the contribution of the Neel surface anisotropy to the effective anisotropy of magnetic nanoparticles of spherical shape cut out of a simple cubic lattice. The effecti…
Effects of nonlinear sweep in the Landau-Zener-Stueckelberg effect
D. A. Garanin, R. Schilling
We study the Landau-Zener-Stueckelberg (LZS) effect for a two-level system with a time-dependent nonlinear bias field (the sweep function) W(t). Our main concern is to investigate…
Superradiance from crystals of molecular nanomagnets
E. M. Chudnovsky, D. A. Garanin
We show that crystals of molecular nanomagnets can exhibit giant magnetic relaxation due to the Dicke superradiance of electromagnetic waves. Rigorous treatment of the superradianc…
Inverse problem for the Landau-Zener effect
D. A. Garanin, R. Schilling
We consider the inverse Landau-Zener problem which consists in finding the energy-sweep functions W(t)=E1(t)-E2(t) resulting in the required time dependences of the level populatio…
