Linear and isotropic magnetoresistance of CoFeSi at x=0.2; 0.4; 0.65
A. E. Petrova, S. Yu. Gavrilkin, V. A. Stepanov +3
We studied the magnetoresistance (MR) of well-characterized samples of CoFeSi at x=0.2, 0.4, and 0.65 at temperatures between 1.8 and 100~K and magnetic fields of 9~T.…
On the Topological Features of the Helical Phase Transition in MnSi
S. M. Stishov, A. E. Petrova, A. M. Belemuk
Many decades of study have revealed very unusual properties of the helical phase transition in MnSi. This situation is briefly described and illustrated in the present note. As one…
Melting and polymorphic transitions in liquid
S. M. Stishov
Review of the author's data, partly still unpublished, on studying of liquid tellurium and cesium are given. No proofs indicating phase transitions in liquids were found. New devel…
On the heat capacity of quantum hard sphere fluid
Sergei Stishov
The thermodynamic properties of the Boltzmann hard sphere system is discussed. It was found that zero point energy decreases with temperature so slowly that it turned out to be an…
On melting of Boltzmann system of quantum hard spheres
S. M. Stishov
Melting of a quantum system of hard spheres has been considered in the case when the effects of Bose and Fermi statistics can be neglected. It has been found that the quantum melti…
Quantum criticality features in the Co doped MnSi
A. E. Petrova, A. M. Belemuk, S. M. Stishov
The mysterious universal line revealing an independence of spin fluctuation contributions to the heat capacity of (Mn,Co)Si on impurity contents and its nature is discovered. This…
