Homework Help: A type 2 superconductor is placed in a small magnetic field

  1. Nov 7, 2011 #1
    A flux quantum is approx. equal to 2*(10)^(-7) gauss cm*cm. A type 2 superconductor is placed in a small magnetic field which is then slowly increased till the field starts penetrating the superconductor. THe strength of the field at this point is 2/pi*(10)^(5) gauss.

    The penetration depth is

    10 angstrm
    1000 angstrm
    314 angstrm

    The applied field is further increased till superconductivity is completely destroyed. The strength of field is 8/pi*(10)^5 gauss. The correlation length of superconductor is
