Investigation of metamorphic conditions and mineralogical changes at green-schist to amphibolite facies transition zone using phase diagrams and compositions of the mineral: a case study from the Kordestan province metabasites

In this paper, metamorphic conditions (T, P and fluid composition) in greenschist to amphibolite facies transition zone are investigated using textural evidence, compositions of the minerals and phase diagrams. Metabasits from the south of Kordestan province were metamorphosed from sub-greenschist to upper amphibolite facies. Field observations and petrography studies show that there are some r...

Thermodynamic features in the H-T plane of superconducting UBe13.

The spin degrees of freedom play an essential role in heavy-fermion superconductivity. In UPt3, not only may spin fluctuations provide the pairing mechanism, but the existence of antiferromagnetic order below T„(with a magnetic moment —0.02ptt) ' allows the possibility of multiple superconducting phases. Similarly, recent magnetic x-ray and neutron-scattering studies of URuzSi2 establish the mi...

Magnetic Properties and Phase Transitions in a Spin-1 Random Transverse Ising Model on Simple Cubic Lattice

Within the effective-field theory with correlations (EFT), a transverse random field spin-1 Ising model on the simple cubic (z=6) lattice is studied. The phase diagrams, the behavior of critical points, transverse magnetization,  internal energy, magnetic specific heat are obtained numerically and discussed for different values of p the concentration of the random transverse field.
