Conventional superconductors are characterized by a relatively low magnetostriction, which
is usually described in frames of a thermodynamic model. 1 In this model changes of the
sample dimensions were calculated by differentiation of an appropriate thermodynamic
potential. The pinning induced mechanism of the magnetostriction was first proposed by
Ikuta et al. 2 in order to explain giant magnetostriction in a Bi2Sr2CaCu2O8 single crystal. A
force, opposite to one which acts on flux lines, acts on the sample and causes the changes …
