Quantifying interactions in arrays of magnetic nanoelements
A natural consequence of increasing storage densities in future bit patterned media and magnetic random access memory (MRAM) is an increased packing density of the constituent magnetic elements. Closer spacing between the elements leads to increased dipolar interactions, which may adversely affect functionality, by demagnetizing stored magnetic information. To solve the optimization problem of achieving highest bit density without affecting magnetic stability we will study theoretically and experimentally the effects of magnetic interactions on magnetic stability of various model systems, such as rectangular arrays of cobalt nanoellipses with different combinations of row and column spacing, fabricated by Kai Liu’s group at UC Davis with electron beam lithography.
