SUMMARY
Modelingofthepropertiessuperconductingmaterialsisdiscussed.Thesepropertiesare
dividedintothreegroups.Firstonearethermodynamicproperties,suchascritical
temperature,energygap,reversiblemagnetizationcurveandthermodynamiccritical
magneticfield,whicharebasedonfundamentalprinciplesofsuperconductingstate.
Secondpropertiesarebasedonthepurityofthesamplesdescribedbythemeanelectron
freepath.Examplesoftheseparametersareupperandlowercriticalmagneticfield,
