Abstract
The strength of the quadrupolar interactions is determined by means of ultrasonic velocity experiments. For the tetragonal symmetry, the ferroquadrupolar terms are strong enough to explain the first-order transition at the Néel temperature. Their actual effects in the magnetic structure are not fully determined.
