Abstract
The result of dc and ac magnetization, heat capacity and magneto-resistance measurements in the polycrystalline and single crystal samples at the stoichiometry, Nd0.75Ho0.25Al2, are presented. Magnetic compensation between the antiferromagnetically coupled Nd and Ho moments in nominal zero field, and the field induced reorientation of the Nd/Ho moments in H = 5 kOe are observed to happen at the same temperature for H parallel [100], [110] and [111] directions. The ac magnetization data also appear to imprint the field-induced moment reversal process in polycrystalline as well as in a single crystal sample (for H || [100]). Intriguingly, the magneto-resistivity data in H = 10 kOe show three sign reversals below Tc.
