The coercive behavior of core/shell nanoparticles

We have studied Co/CoO nanoclusters with a core‐shell morphology produced by deposition from a gas aggregation source onto substrates in UHV and by theoretical modeling using the Monte Carlo simulation technique. The simulations give shifted hysteresis loops, in agreement with the experimental findi...

Zusammenfassung:We have studied Co/CoO nanoclusters with a core‐shell morphology produced by deposition from a gas aggregation source onto substrates in UHV and by theoretical modeling using the Monte Carlo simulation technique. The simulations give shifted hysteresis loops, in agreement with the experimental findings and result to a reversal in the size dependence the exchange bias field at low temperatures.
