摘要：

Describe the detection by neutron diffraction of two new ordered phases in LiH, produced by nuclear adiabatic demagnetization in a high field parallel to a crystalline axis. The phases are antiferromagnetic at positive temperature and ferromagnetic at negative temperature. A 2-dimensional neutron detector reveals that the domains are anisotropic, in the form of pancakes perpendicular to the field, both in the ferromagnet as expected, and in an antiferromagnet. Approximate values are derived for the longitudinal and transverse dimensions of the domains.
