摘要：

It is argued that the stress caused by vortex cores in the mixed state of superconductors may result in a measurable field-dependent contribution to the free energy and magnetization. For sufficiently strong stress dependence of the critical temperature, partial derivative T-c/partial derivative p, this contribution may result in the "second peak" in the field dependence of the reversible magnetization, the effect often masked by vortex pinning and creep.
