The superconducting state of the cuprates in the presence of a magnetic 5eld has been investigated very actively in the past few years through measurements of electrical and thermal transport, ac conductivity, speci5c heat, and other quantities. The observed behavior is not well understood; it probe

✦ Synopsis
The nucleation of the superconducting phase has been analyzed by solving the linearized Ginzburg-Landau equation in cylindrical coordinates. The orbital quantum number (L) degeneracy of the nucleation energy on the H,z(T) line has been used to build a solution \zr = CCL@L corresponding to the novel 'concentric' vortex state. Different superconducting order parameter @I2 patterns have been simulated.

We obtain expressions for thermal conductivity and ultrasonic attenuation coefficient in unconventional superconductors in the vortex state in the vicinity of B = H i(T~ where B is the magnetic induction and H i c2 c2(T) is the upper critical field when ~ is parallel to the crystal axis i.
We investigated the sample size dependence of the types of vortex states, i.e., multivortex states or giant vortex states, in mesoscopic superconducting squares by using the temperature dependence of vortex expulsion fields. The giant vortex states are stable in small samples and at high magnetic fi
