On the possibility of the temperature-induced ferromagnetism in TiBe2 and other itinerant magnets

This paper proposes possible temperature-induced ferromagnetism (TIF) in TiBe2, TiBe2-xCux and other itinerant magnets. The value of the critical field Hcr for the existence of TIF in TiBe2, evaluated on the basis of the author's and others' experimental results, coincide with the value Hcr congruent 610 G predicted by Enz within the spin density wave theory of itinerant antiferromagnetism (AFM). The possibilities of the existence in TiBe2 of the TIF mechanism of spin fluctuations around the AFM mode as predicted by Moriya, and of the temperature-induced noncompensated itinerant AFM, i.e. ferromagnetism, are considered
