Vortex-lattice melting and paramagnetic depairing in the nematic superconductor FeSe

The full H-T phase diagram in the nematic superconductor FeSe is mapped out using heat-capacity and thermal-expansion measurements down to 0.7 K and up to 30 T for both field directions. A clear thermodynamic signal of an underlying vortex-melting transition is found in both datasets and could be fo...
