Abstract
Diamagnetically coupled magnetic field can be used as a probe of nodal positions in unconventional superconductors. The heat capacity depends on the angle $Ï_0$ between the magnetic field and the nodal directions. We show that the anisotropy $C(Ï_0)$ persists even in systems with strong paramagnetic coupling to the electrons's spins.
