文摘
- •
A temperature field is induced in a core-shell wire passed by an dc electric current.
- •
The stresses due to the temperature gradients increase with current intensity.
- •
The supplementary magneto-elastic anisotropy changes the magnetic behavior of system.
- •
An increase of the coercive field with the passing current intensity was observed.
