| 摘 要： | 摘要：制备了镍基化合物GdONiBi,并且得到其超导转变温度为45K.通过用Sr元素部分的替代Gd元素向该物质中引入空穴,得到了一种新的超导体Gd0-9Ni0-1其转变温度为47K.两种镍基化合物超导体正常金属态的电阻率均显示出金属行为.通过对其磁电阻效应的研究发现其磁电阻效应显示出与铁基超导体不同的行为,表明两者之间的超导机制可能存在差异.

| Abstract: | The nickel-based compound GdONiBi was successfully synthesized with superconducting transition temperature about 4.5 K. By partially substituting the element Gd with Sr to introduce holes into the material,a new superconductor Gd0.9Sr0.1ONiBi was obtained with critical temperature about 4.7 K. The normal state resistivity in nickel-based samples shows a metallic behavior. The magnetoresistance measurements show a different behavior compared to those in iron-based compounds which may indicate that the mechan... |
