Abstract
The magnetic phase diagram for the RMA system DyxY1-xAl2 is determined. For x ≤ 0.30 a PM/SG transition is found, while for x > 0.30 a CSG phase exists. No long range magnetic order appears, yet the initial susceptibility diverges at and below the PM/CSG transition. Scaling analysis indicates phase transitions, and the critical exponents β, γ, δ, δ1 and φ and βs, γs and δs have been determined.
