SmCo is a permanent magnetic material having peculiar characteristics. It can be used in different application field: electronic, environmental control and medicine. SmCo nanoparticles could be used in hyperthermia, particular treatment of cancer cell. Hyperthermia is the procedure that increases the local temperature of cancer cells in the range of 40°- 43° C. Using this temperature management, the number of cancer cells could be reduced. SmCo nanoparticles will be produced by Pulsed Laser Ablation (PLD) or Matrix Assisted Pulsed Laser Deposition (MAPLE) techniques and the nanostructures will be characterized by using X-Ray Diffraction, Scanning Electron Microscopy and magneto-optics measurements. The analysis is proposed as attempt for the use of SmCo nanoparticles in the hyperthermia field.
