“…15) Other important factors include Joule heating effects during current-induced magnetization switching experiments, 16) magnetic dead layers, 17) and defects formed during nanofabrication. 18) One suitable experimental method can be the waiting time measurements where the probability of magnetization switching is measured for a given waiting time at an applied magnetic field, not current, just below the switching field and the results are fitted with the Neel-Brown equation to extract E M . 19) It is important to point out that, since the results calculated in this study are essentially based on micromagnetic simulation, the accuracy of which has been confirmed substantially in recent years in general magnetics research, in particular magnetic recording, the present results should provide a good guide in analyzing experimental results as well as in designing magnetic cells in advanced magnetic devices such as high density MRAM.…”

Methods are described in this study to predict the magnetic configuration at the saddle point in nanostructured cells of single magnetic thin films and synthetic antiferromagnets. The prediction is done indirectly by calculating the self-demagnetizing field at the saddle point, which is then compared with the value calculated under the ideal single domain state. The saddle point magnetic configuration in the single magnetic thin films deviates more from the ideal single domain state than in the synthetic antiferromagnets. As the cell geometry varies from rectangle to ellipse, the deviation decreases monotonically in the single magnetic thin films, while it remains nearly constant in the synthetic antiferromagnets.

A method is proposed to calculate the magnetic energy barrier of nanostructured cells of synthetic ferrimagnets. An important feature of the method is the use of an equation for the total energy that contains the magnetostatic fields at the saddle point as parameters of the energy equation. With no suitable methods of accessing the magnetic configuration at the unstable saddle point, it is difficult to obtain the saddle point magnetostatic fields. This difficulty is overcome with the use of equations that link the magnetostatic fields at the saddle point and critical fields, which are readily obtained by micromagnetic simulation. The present method is essentially based on the micromagnetic simulation, and, therefore, it should provide accurate results for the magnetic energy barrier. A contour diagram showing the thermal stability parameter is constructed as a function of the cell geometry and the thickness asymmetry, and the result should be of great value in designing magnetic cells for high density magnetic random access memory.
