Description
In this thesis we describe a pulsed field device with which we obtain magnetization curves up to 450 kOE at all temperatures between 1. 6 and 300. We have studied the 'spin-flopping'(and therefore the anisotropy) in MnF2 versus temperature, below the Neel point. We have also studied the antiferromagnets MnSO4. and MnSO4.H2O which have revealed saturation fields respectively of 250 kOE and 320 kOE. (author)

Ce memoire est consacre a la fabrication et a la mise au point d'un appareillage utilisant la decharge d'une batterie de condensateurs, afin de faire des mesures d'aimantation en champs pulses jusqu'a 450 kOE a toute temperature entre 1,6 K et 300 K. Nous avons etudie le deplacement de la transition de 'spin-flopping' dans MnF2 en fonction de la temperature et nous en avons deduit la variation de la constante d'anisotropie en fonction de T au-dessous du point de Neel. Nous avons egalement fait l'etude magnetique des antiferromagnetiques MnSO4 et MnSO4.H2O et nous avons mis en evidence la saturation de ces deux substances pour des champs respectifs de 250 kOE et 320 kOE.
