The spin-lattice relaxation time, T1, of conduction electrons is measured as a function of temperature and magnetic field in MgB2. The method is based on the detection of the z component of the conduction electron magnetization under electron spin resonance conditions with amplitude modulated microwave excitation. Measurement of T1 below Tc at 0.32 T allows to disentangle contributions from the two Fermi surfaces of MgB2 as this field restores normal state on the Fermi surface part with… Expand
