What is recorded here?
Proved that the stated one- and two-dimensional isotropic finite-range Heisenberg models cannot sustain ferromagnetic or antiferromagnetic order at nonzero temperature.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The record is the exact two-author 1966 letter together with its published erratum boundary. The theorem depends on dimensionality, symmetry and interaction assumptions; it does not forbid all phase transitions or all order in low-dimensional systems.
