Abstract EN
Fourfold magnetic nanoparticles, created from nanowires or in the form of an open square, offer the possibility of creating quaternary memory devices with four unambiguously distinguishable stable states at remanence.
This feature, however, has been simulated for single magnetic nanoparticles or clusters with interparticle distances similar to the nanoparticle dimensions.
For the possible use in bit-patterned media, it is important to understand the scaling behavior of the stability of the additional intermediate states with the interparticle distance.
The paper investigates exemplarily nanoparticles of two shapes which were found to be optimum to gain four states at remanence.
For clusters of these particles, the probability of reaching the additional intermediate states in all particles in the same field region is strongly reduced with decreased interparticle distance.
The differences between both shapes indicate possible solutions for this problem in the form of new nanoparticle shapes.
