 Abstract: The linear magnetic specific heat, Cm = γT, of (La0.92Gd0.08)Al2 is reduced in a magnetic field H. For H ≥ 1 tesla, γ(H) is explained within the RKKY model. The steep decrease of γ already in small fields (H ≤ 0.1 tesla) is compared to the strong depression of the susceptibility and interpreted as being due to the blocking of superparamagnetic clouds.
