Abstract: The work is related with the finding out of magnetic phases in stronglyanisotropic high-temperature superconductor Bi1,7Pb0,3Sr2Ca2Cu3O10-d in thetemperature region where the superconductor is in the normal state.
It wasstudied the temperature dependence of the paramagnetic probe EPR line width.
Inthe normal state at T>Tc near 175 K it was revealed a pick in the temperaturedependence of line width.
In this region it was observed the time increase ofthe line width with the characteristic time ~ 17 min.
This shows thepossibility of magnetic phase formation in this material.
