Title:
Elastic Torsion Effects in Magnetic Nanoparticle Diblock-Copolymer Structures 
Abstract:
Magnetic properties of thin composite films, consisting of non-interacting polystyrene-coated $\gamma$ - Fe 2 O 3 (maghemite) nanoparticles embedded into polystyrene-block-polyisoprene P(S- b -I) diblock-copolymer films are investigated. Different particle concentrations, ranging from 0.7 to 43 wt%, have been used. The magnetization measured as a function of external field and temperature shows typical features of anisotropic superparamagnets including a hysteresis at low temperatures and blocki...    »
