Current Annealing Induced Magnetic Anisotropy Joule Heat Tempering Features

Effects of transverse magnetic anisotropy on current-induced spin switching.

Spin-polarized transport through bistable magnetic adatoms or single-molecule magnets (SMMs), which exhibit both uniaxial and transverse magnetic anisotropy, is considered theoretically. The main focus is on the impact of transverse anisotropy on transport characteristics and the adatom's or SMM's spin. In particular, we analyze the role of quantum tunneling of magnetization (QTM) in the mechan...

Annealing and Tempering for Sampling and Counting

iii ACKNOWLEDGEMENTS I would like to thank my advisors Dana Randall and Eric Vigoda for their guidance and support, which they gave generously. I was fortunate to have the opportunity to work with two of the leading researchers in my field. Dana never ceased to surprise me with her quick insights and ability to get to crux of a problem. I thoroughly enjoyed working with Eric and am always inspi...

Hybrid parallel tempering and simulated annealing method

In this paper, we propose a new hybrid scheme of parallel tempering and simulated annealing (hybrid PT/SA). Within the hybrid PT/SA scheme, a composite system with multiple conformations is evolving in parallel on a temperature ladder with various transition step sizes. The simulated annealing (SA) process uses a cooling scheme to decrease the temperature values in the temperature ladder to the...

Field-induced magnetic anisotropy in La0.7Sr0.3CoO3

Magnetic anisotropy has been measured for the ferromagnetic La0.7Sr0.3CoO3 perovskite from an analysis of the high-field part of the magnetization vs. field curves, i.e., the magnetic saturation regime. These measurements give a magnetic anistropy one order of magnitude higher than that of reference manganites. Surprisingly, the values of the magnetic anisotropy cal-
