dc.description.abstract | We investigate the critical behaviour of the chemical potential and average
occupation numbers using the extended s—f model with intersite Cooper
pairing for systems with fluctuating valence. The model is able to describe
phase transitions from normal ferromagnet to normal paramagnet at Τ = Τc,
from superconducting paramagnet to normal paramagnet at Τ = Ts, as well
as reentrant phase transitions with three critical temperatures Τs1, Tc and
Τs2 (Ts1 < Tc < Τ52). Present investigation, as well as recent results obtained
for another models suggest one-to-one correspondence between critical
temperatures of the system and kinks appearing in the temperature dependence
of the chemical potential and average occupation numbers. This, in
turn, indicates a possibility to apply the measurement of the chemical potential
vs. temperature as an experimental universal tool when looking for
phase transitions in solids. | pl_PL |
