镧在高压下原子体积减小,导带中f成分增加,这是促使镧在高压下超导转变温度增加较大的重要因素。某些镧合金及化合物的超导转变温度的增加与纯镧加压等当。采用特殊手段促进上述有利因素以制成含镧的超导新材料是值得重视的。 The atomic volume of lanthanum decreases under high pressure and the f component increases in the conduction band, which is an important factor that causes the increase of superconducting transition temperature of lanthanum under high pressure. Some lanthanum alloys and compounds increase the superconducting transition temperature with pure lanthanum pressurization. The use of special means to promote the above factors to make lanthanum-containing superconducting new materials is worthy of attention.
