We have investigated the anisotropic properties of CuMn, AgMn, CuMnAu x, AuFe spin glasses at T < Tg by performing transverse susceptibility (χ⊥) measurements in zero and small (≾ 1 kG) static field H0 //z. We demonstrate that, in presence of a remanent magnetization σ initially developed along z, the response of the spin system to a small transverse (⊥ z) field involves a collective rotation of the spins which is fully characterized by a macroscopic anisotropy field HA for small deviations. At a given temperature the anisotropy energy K = σHA is found independent of σ. A slight decrease of K with temperature is evidenced in the investigated range T ≾ T g/3. At T <<; Tg the same value for K is found to explain χ⊥, NMR and ESR (both in prese...
