This paper describes a model for magnetization reversal in polycrystalline Ferromagnetic/Antiferromagnetic exchange biased bilayers. We assume that the exchange energy can be expanded into cosine power series. We show that it is possible to fit experimental asymmetric shape of hysteresis loops in exchange biased bilayer for any direction of the applied field. The hysteresis asymmetry is discuss...
In this study, the substituent effect on the electronic, spectroscopic properties and thermodynamic parameters of neutral and oxidized states of ferrocylidene acetophenone complexes was investigated by adopting the hybrid meta exchange-correlation functional of M06-2X. The frontier orbitals and the highest occupied molecular orbitals–lowest unoccupied molecular orbitals gaps of the substituted ...
Consider a classical system in contact with a constant temperature heat bath where some degree of freedom of the system can be controlled. Manipulation of this degree of freedom results in an expenditure of some amount of work, a change in the energy and free energy of the system, and an exchange of heat with the bath. Let 1 be a parameter specifying the current value of the controllable degree...
We present a simple, analytic and straightforward method to elucidate the effects produced by polytropic fluids on any other gravitational source, no matter its nature, for static spherically symmetric spacetimes. As direct application, we study interaction between polytropes perfect coexisting inside self-gravitating stellar object
