DRESSLER, S. ... et al., 2000. Suppression of the martensitic phase transition and the effect on superconductivity in HfV2. Solid State Communications, 113 (11), pp.649-651.
HfV2 has been classified as a heavy Fermion system with a superconducting ground state characteristic of strong electron
phonon coupling. An instability of the lattice at 117 K is believed to significantly influence the onset of superconductivity below
,9 K. Neutron diffraction and magnetisation measurements carried out on a specimen in which the structural phase transition
has been suppressed reveal that the superconducting transition is only slightly reduced to 8:1 ^ 0:1 K:
