Impurities in singlet magnets
Shender E. F.
It is shown that doping of certain singlet magnets with small amounts of magnetic impurities alters radically the state of the magnetic system of the matrix. In particular, ferromagnetic order may be produced in substances that are paramagnetic in the absence of impurities even at zero temperature. The impurity-induced transition from the ferromagnetic state into the paramagnetic state is also considered.
