During the destruction of superconductivity through heating, an each heated career increases its thermal vibration. If the effective velocity of vibration is v t , its kinetic energy: E k = mv2 t 2 ≃ ∆ 0 (8.1) Only a fraction of the heat energy transferred to the metal is consumed in order to increase the kinetic energy of the electron gas in the transition metals. Another part of the energy will be spent on the magnetic interaction of a moving electron. 92 Science Publishing Group

Chapter 8 Another Superconductors At contact with the d-shell electron, a freely moving electron induces onto it the magnetic field of the order of value: H ≈ e v rc 2 c . (8.2) The magnetic moment of d-electron is approximately equal to the Bohr magneton. Therefore the energy of the magnetic interaction between a moving electron of conductivity and a d-electron is approximately equal to: E µ ≈ e2 2r c v c . (8.3) This energy is not connected with the process of destruction of superconductivity. Whereas, in metals with a filled d-shell (type-I superconductors), the whole heating energy increases the kinetic energy of the conductivity electrons and only a small part of the heating energy is spent on it in transition metals: E k E µ + E k ≃ mv t h a B. (8.4) So approximately E k E µ + E k ≃ a B L 0 . (8.5) Therefore, whereas the dependence of the gap in type-I superconductors from the heat capacity is defined by Eq.(7.3), it is necessary to take into account the relation Eq.(8.5) in type-II superconductors for the determination of this gap dependence. As a result of this estimation, we can obtain: ∆ 0 ≃ Θγ 2 ( where 1/2 is the fitting parameter. ) Ek E µ + E k ≃ Θγ 2 ( aB L 0 ) 1 2 , (8.6) Science Publishing Group 93
