Abstract
Spontaneous and magnetic field induced incommensurate – commensurate magnetic phase transitions have been studied in Tb1-x
Er
x
Ni5 compounds near the critical concentration x
c = 0.125. Compounds crystallize in the hexagonal CaCu5 type phase (P6/mmm space group). In compounds with x ≥ x
c the magnetic order is a commensurate ferromagnetic one. The samples with x < x
c have an incommensurate structure that is a fan like magnetic structure and described by two propagation vectors. An incommensurate – “lock in” magnetic transition takes place at 10 K at cooling regime.
