✦ Synopsis
Behaviour of longitudinal magnetic dipolar fluctuations in vicinity of the quadrupolar phase transition point in the paramagnetic range of some thulium cubic intermetallic compounds has been discussed. It was shown that halfwidth of the magnetic central peak at the temperature of quadrupolar phase transition diminishes evidently in a static external magnetic field. Temperature dependence of the width of the magnetic central peak in a strong magnetic field shows up the minimum value at the quadrupolar phase transition point. The analysis of the width of the central magnetic mode in scattering experiments provides a new method of observation of the quadrupolar phase transition.
