B. Ghosh, S. Kumar, A. Poddar, C. Mazumdar, S. Banerjee, V. R. Reddy, and A. Gupta

The effects of particle size, structure, microstrain, and cation distribution on magnetic property of nanosized Ni_0.35Zn_0.65Fe₂O₄ prepared through high-energy ball milling have been explored by a wide variety of experimental technique namely, x-ray diffraction, high-resolution transmission electron microscopy, dc magnetization measurement, and Mössbauer spectroscopy.

Magnetization reversal of bit patterned media: Role of the angular orientation of the magnetic anisotropy axes

P. Krone, D. Makarov, M. Albrecht, and T. Schrefl

Micromagnetic modeling was performed to study the influence of an angular dispersion of the magnetic anisotropy axis on the reversal behavior of tilted bit patterned media with an areal density of about 1 Tbit/in.².

Modeling the performance of magnetic nanoparticles in multimodal cancer therapy

S. Purushotham and R. V. Ramanujan

Composite magnetic nanoparticles (MNPs) consisting of an MNP core and drug loaded polymer shell can increase the efficacy of cancer therapy by overcoming several limitations of conventional hyperthermia and chemotherapy. Factors influencing power output in an alternating magnetic field for superparamagnetic γ-Fe₂O₃ and Fe₃O₄ iron oxide MNP were studied and the optimum MNP properties for in vivo magnetic hyperthermia were identified.
