Temperature dependences of thermal conductivity, thermal diffusivity, enthalpy, heat capacity, density and coefficient of linear expansion of 7 brands of modern magnetically rigid materials have been studied. The experiments were carried out by dilatometry, differential scanning calorimetry, and also by a laser pulse method for determining the thermal diffusivity. First, experiments were carried out to determine the thermophysical properties of samples with remanent magnetization. After that, the samples were demagnetized by heating to temperatures exceeding the Curie temperature, after which the thermophysical properties of the demagnetized samples were measured. The obtained results allow us to state, that the presence of remanent magnetization in the materials studied does not lead to a distinguishable change in the thermophysical properties considered in this investigation.
