The problem is the measurement of dynamic characteristics of refractory materials at high temperatures (more than 2300K).

In order to reach this goal a unique thermostat named TS-3000K for neutron scattering experiments was designed. It allows the heating of volumic (as cylinder of =81 mm, h=104 mm, t=1mm) metal...

Is there an analog of the Matthiessen's rule violation for magnetization (susceptibility)?

We know that the so-called Matthiessen's rule is valid when different scattering processes can be considered independent. In this case it says that the total resistivity R is a sum of different...
