Specific heat versus field for LiFe1−xCuxAs

Specific Heat Exponent of Random – Field Ising Magnets

Zero – temperature simulations of the 3 d = random–field Ising model (RFIM) with a bimodal distribution suggest that the specific heat's critical behaviour is consistent with an exponent 0 α ≃ . Τhis is compatible with experimental measurements on random – field and diluted – antiferromagnetic systems and, together with previous simulations on the Gaussian RFIM, settles a clear picture for the ...

Field Dependent Specific-Heat of Rare Earth Manganites

The low temperature specific heat C(H) of several rare-earth manganites (La0.7Sr0.3MnO3, Nd0.5Sr0.5MnO3, Pr0.5Sr0.5MnO3, La0.67Ca0.33MnO3, La0.5Ca0.5MnO3, La0.45Ca0.55MnO3 and La0.33Ca0.67MnO3) was measured as a function of magnetic field. We observed behaviour consistent with thermodynamic expectations, i.e., C(H) decreases with field for ferromagnetic metallic compounds by an amount which is ...

Magnetic Field Dependence of Electronic Specific Heat in

The specific heat of electron-doped Pr1.85Ce0.15CuO4 single crystals is reported for the temperature range 2 10 K and magnetic field range 0 10 T. A non-linear magnetic field dependence is observed for the field range 0 2 T. Our data supports a model with lines of nodes in the gap function of these superconductors. Theoretical calculations of the electronic specific heat for dirty d-wave, clean...

A nonlocal phase - field model with nonconstant specific heat †

We prove the existence, uniqueness, thermodynamic consistency, global boundedness from both above and below, and continuous data dependence for a solution to an integrodifferential model for nonisothermal phase transitions under nonhomogeneous mixed boundary conditions. The specific heat is allowed to depend on the order parameter, and the convex component of the free energy may or may not be s...
