BACKGROUND The purpose of this study was to observe the effect and feasibility of hyperthermia and the influence of heat on surrounding organs in a VX2 rabbit liver model exposed to an alternating magnetic field after embolization with ferromagnetic nanoparticles. METHODS Forty rabbits containing implanted hepatic VX2 carcinomas were divided into four groups, each containing ten rabbits. Four...

We analyze the magnetic excitations of a spin-1/2 antiferromagnetic Heisenberg model with alternating nearest neighbor interactions and uniform second neighbor interactions recently proposed to describe the spin-Peierls transition in CuGeO3. We show that there is good agreement between the calculated excitation dispersion relation and the experimental one. We have also shown that this model rep...

Recent progress in the development of high-frequency (HF) magnetic materials and devices requires HF imaging field response with high spatial resolution. In this work, we proposed Alternating Magnetic Force Microscopy (A-MFM) a superparamagnetic tip to image energy near sample surface. frequency from 100 kHz 1 GHz was emanated by writing head used for perpendicular recording. Applied is amplitu...

Hyperthermia is one of the first applications of nanotechnology in medicine by using micro/nano magnetic particles that act based on the heat of ferric oxide nanoparticles or quantum dots in an external alternating magnetic field. In this study, a two-dimensional model of body and tumor tissues embedded is considered. Initially, the temperature distribution is obtained with respect to tumor pro...
