Abstract
The magnetic field vs. temperature (H - T) phase diagram is determined from linear χ⊥0 and nonlinear χ⊥2 susceptibilities perpendicular to H for metallic spin glasses AuFe (4 at. % Fe) and AgMn (4 at. % Mn). The χ⊥2 signal has a round maximum at T = T1 (H) and below T1 (H) the imaginary part of χ⊥0 increases rapidly around T = T2 (H).
