Magnetic Effects in Films of Mn-12-Acetate Academic Article

abstract

• 2016 The Physical Society of Japan. Pulsed laser deposition has been optimized to deposit Mn12-acetate films. Extensive DC and AC susceptibility measurements on these films reveal the presence of two peaks due to (i) a single molecule spin blocked species below 3 K as in crystalline Mn12-acetate, and (ii) a magnetic species at 28 K due to significant additional interactions (below 40 K). Lattice deformation and random distribution of magnetic ions resulting from laser ablation may account for the presence of a new species with enhanced magnetic anisotropy leading to a higher transition temperature. Results suggest that the high temperature species stabilizes the spin blocked species and the two-species system may display an exchange bias effect.
