N2 - The temperature dependence of coercive force Hc(T) of pressed powders of ferromagnetic half metal CrO2 is compared to the temperature dependence of the maximum field of positive tunneling magnetoresistance Hp(T). It is established that the multidomain alters the nature of the reverse magnetization oftransport channels and violates relation Hp ≈ Hc at low temperatures (4.2–70 K).

AB - The temperature dependence of coercive force Hc(T) of pressed powders of ferromagnetic half metal CrO2 is compared to the temperature dependence of the maximum field of positive tunneling magnetoresistance Hp(T). It is established that the multidomain alters the nature of the reverse magnetization oftransport channels and violates relation Hp ≈ Hc at low temperatures (4.2–70 K).
