Abstract
Magnetic properties of metallic alloys used in biomedical industry are important for the magnetic resonance imaging (MRI). If the alloys were to be used for long term implants or as guiding devices, safety of the patient as well as the medical staff has to be ensured. Strong response to the external magnetic field can cause mechanical damage to the patients body. In this paper we present magnetic susceptibility of nickel rich, ternary NiTiPt and NiTiEr to static magnetic field. We show that the magnetic susceptibility of these radiopaque alloys has values in low paramagnetic region comparable to the binary nickel-titanium. Furthermore, we studied the effect of the ther mal and mechanical treatments on magnetic properties. Despite deviation from linear M(H) treated samples spanning small region around H = 0, the linearity of the M(H) and x = dM=dH values suggest that these ternary alloys are safe to use under MRI conditions.
