日本关西大学系统理工学部佐伯拓等人发现,用一种特殊方法制成的铝粒子,具有铁磁性。这方法就是在铝粉中注入水,搅拌之,并用脉冲激光照射,制成粒径约为19nm的多晶纳米粒子,再与纳米银浆混合成粘土状,制成板状铝材料,经测定,具有铁磁性。脉冲激光处理用的频率为20kHz,经X-射线衍射证明,所制成的铝 Japan Kansai University Department of Systems Science and Technology Zuo Bo Tuo and others found that with a special method of aluminum particles made with ferromagnetic. This method is to inject water into the aluminum powder, stirring, and pulsed laser irradiation, made of polycrystalline nanoparticles with a particle size of about 19nm, and then mixed with the nano silver paste into a clay-like, made of aluminum plate material, determined , With ferromagnetic. Pulse laser processing with a frequency of 20 kHz, as evidenced by X-ray diffraction, was made of aluminum
