摘要：

Controllable by an external magnetic field, ferromagnetic shape memory materials reveal a high potential for actuators in biomedical applications. Simulated body fluid (SBF) and cell tests were performed to assess the biocompatibility of Fe70Pd30 ferromagnetic shape memory thin films as grown on MgO substrates. Calcium-phosphate aggregates were detected on the film surface after soaking in SBF. Biocompatibility tests with NIH 3T3 fibroblasts revealed adhesion and proliferation on the film surface but morphological modifications with a reduced cell size became evident as well as changes in cell viability for continuous and noncontinuous FePd films. The results are compared to FePd on SiO2. (C) 2010 American Institute of Physics. [doi:10.1063/1.3435260]
