Magnetic phase diagram of CePdAl for B ∥ c obtained from measurements of different properties. The subscript i for α_i and λ_i denotes the different axes a or c. Open circles indicate the approximate temperature of the broad shoulders of C_4f/T below T_N, gray squares the position of the maxima of the Schottky anomalies, and red open diamonds the temperature of the C_4f maximum. The inset shows an enlarged view of the AF₂ and AF₃ phases. (b) Entropy S(B) at different fixed temperatures. (c) Frustration parameter f_S = T_S/T_N vs. B. For B >B_c3, C_4f/T at T = 0.5 K is plotted against B. All lines are guides to the eye. Figure reproduced with permission from Lucas et al., Ref. [64]. Copyright 2017 by the American Physical Society.
