Huge piles of wood and stone,
And glance at each amorphous mass,
Whose cumbrous weight has crushed the grass,
With half resentful groan.

In science:

Nevertheless, we expect our results to be relevant for a wide class of amorphous ferromagnets, and in particular it would be interesting to check them against experiments on polycrystals, in which dipolar forces are weak and anisotropy is the dominant form of disorder.
Critical Hysteresis from Random Anisotropy
The ma jority of investigations of amorphous random anisotropy systems reports the low-temperature phase to be either a spin-glass phase or a so called correlated spin glass phase, in terms of the phenomenological theory often used for the interpretation of data.
Critical properties of random anisotropy magnets
Therefore the experiments indicate the absence of a ferromagnetic phase for amorphous systems in general, with the possibility of ferromagnetism for crystalline compounds with weak random anisotropy.
Critical properties of random anisotropy magnets
This distribution mimics an amorphous system without any preferred directions.
Critical properties of random anisotropy magnets
The cubic distribution corresponds to a situation when an amorphous magnet still “remembers” the initial cubic lattice structure in spite of the random anisotropy or describes crystalline compounds with random but restricted anisotropy.
