Specific heat of EuxSrl_xTe
In this paper, we report on measurements of the specific heat C of single-crystalline EuxSrl_xTe at temperatures between 60 mK and 15 K and in magnetic fields up to 6 T. Pure antiferromagnetic EuTe shows unusual critical behavior in the vicinity of the N6el temperature T N = 9.8 K with a positive critical exponent instead of the 3d-Heisenberg exponent c~---0.12. Possible reasons for this discre...
متن کاملSpecific heat of nanocrystals
The present study extends the Einstein model for heat capacity of solids to nanoclusters. In the case of small phases the contribution of surface energy to overall thermodynamic properties of the system is essential. On that physical background, the heat capacity depends on the size of cluster through its interface energy. Employing the same relation between Einstein temperature and the cluster...
متن کاملSpecific Heat of YbNi4Si Compound
The specific heat of YbNi4Si has been analyzed considering the electronic contribution and the lattice contributions in frames of the Debye model. Based on the specific heat measurements, the electronic specific heat coefficient γ = 25 mJ mol−1 K−2 and the Debye temperature θD = 320 K were derived. This small value shows that YbNi4Si cannot be classified as a heavy fermion system. These studies...
متن کاملconstruction of an escherichia coli-specific heat-inducible expression plasmid
purpose: in order to express human granulocyte-macrophage colony stimulating factor (hgm-csf) under heat shock. materials and methods: two expression plasmids were constructed based on pbc(sk) plasmid. the expression cassettes in the two plasmids are equipped with a 75 base pair fragment, derived from the pl promoter of the bacteriophage lambda (λ). the plasmids also contain a temperature muta...
متن کاملSpecific Heat in Superfluid and Normal Phase
The calculation of the 4He energy and specific heat is carried out in a wide temperature range within the two-time temperature Green functions approach. The approximation improving the random phase approximation is developed providing the correct behaviour of the calculated specific heat at the temperatures 0 < T/Tc < 0.65 and T/Tc > 1.32 where Tc stands for the phase transition point.
