I am reading this paper; at page 12, it saids:

Lockwood et al. (1986) found that the recovery time was independent of rigidity in the range ~ 2 to ~ 5 GV

what is GV? I thought that rigidity was measured in T m (Tesla meter).

"GV" is gigavolts.

The Handbook of Geophysics (slightly older version here) explains it:

The magnetic rigidity P of a particle is a measure of its resistance to a magnetic force that deflects the particle from a straight-line trajectory. The rigidity, with units of momentum per unit charge, is defined as

$P = \frac{pc}{q}$

where q is the charge of the particle. If pc is electron volts, then q is the number of electronic charge units and P is in volts. Convenient units are MV ($10^6$ V) and GV ($10^9$ V.

Note that a factor of $c$ was added to the over-the-line 'momentum' to give it energy units.
