Thermal fluctuations and longitudinal relaxation of single-domain magnetic particles at elevated temperatures
D. A. Garanin, O. Chubykalo-Fesenko
We present numerical and analytical results for the swiching times of magnetic nanoparticles with uniaxial anisotropy at elevated temperatures, including the vicinity of T_c. The c…

Saddle index properties, singular topology, and its relation to thermodynamical singularities for a phi^4 mean field model
D. A. Garanin, R. Schilling, A. Scala
We investigate the potential energy surface of a phi^4 model with infinite range interactions. All stationary points can be uniquely characterized by three real numbers $α_+, alpha…
