        The nature of non-crystalline materials causes the local potential energy of a cluster of atoms or molecules to vary significantly in space. Different configurations of an ensemble of atoms in a metallic glass lead therefore to a distribution of elastic constants which also changes in space. This is totally different to their crystalline counterparts, where a long-range order exists in space and therefore a much more unified elastic modulus is expected. Using atomic force acoustic microscopy, we present data which show that the local so-called indentation modulus M indeed exhibits a wide distribution on a scale below 10 nm in amorphous PdCuSi, with ¦¤M/M¡Ö30%. About 104 atoms are probed in an individual measurement. Crystallized PdCuSi shows a variation that is 10¨C30 times smaller and which is determined by the resolution of the microscope and by the polycrystalline structure of the material.
