Neutron diffraction and susceptibility measurements have been performed
to investigate the anomalous transition from antiferro- to ferromagnetic
order which takes place in the ternary intermetallic compound TbNiAl when
Ni is substituted for Cu within the same crystal structure. The transition
is anomalous because 1) a few per cent of Cu already suppresses antiferromagnetism,
2) both ferro- and antiferromagnetic types of order coexist in different
“domains" in the transition range 
, and 3) the balance between
both types of domains further depends on temperature.
