Measurements of the latent heat of thallium connected with the transition, in a constant external magnetic field, from the supraconductive to the non-supraconductive state

摘要: Abstract Calorimetric experiments were performed on thallium in connection with the transition, a constant magnetic field, from supraconductive to non-supraconductive state. A definite latent heat was measured. The values found compared thermodynamic theory. From experimental data proof is deduced that passing threshold value no irreversible entropy change occurs. suggestion made as behaviour of lines force (partly) body when temperature being changed.
