摘要：

The time derivatives of magnetisation for intermetallics RCo2 (R = Y, Lu, Tm, Er, Ho, Dy) with metamagnetic itinerant d-subsystem were measured in pulsed magnetic fields up to 300 T using an explosive-driven generator. Sharp maxima on dM/dt connected with a jump-like magnetisation or demagnetisation of the d-subsystem were observed, The results obtained are compared with estimates made from the measurements on substituted compounds.
