Our measurements of 
Te NMR relaxations reveal an enhancement of electronic spin fluctuations above 
~T, leading to their divergence in the vicinity of the metamagnetic transition at 
~T, below which field-reinforced superconductivity appears when a magnetic field (
) is applied along the crystallographic 
axis. The NMR data evidence that these fluctuations are dominantly longitudinal, providing a key to understanding the peculiar superconducting phase diagram in 
, where such fluctuations enhance the pairing interactions.
