摘要: We study the influence of porosity on domain structure cobalt antidots thin films with controlled and circular defects 20, 40 60 nm diameter. Micromagnetic simulations, combined First-order reversal curves analysis classical magnetometry measurements, have been used to track evolution magnetic configurations. The found coercivity enhancement increase pore diameter is correlated reversibility. Moreover, we that when pores increases domain-domain interactions become dominant.
