A unidirectional magnetotransport anisotropy observed in thin films of exchange-biased ferromagnetic manganites is used to measure temperature dependence of exchange bias in these structures. Values of both the exchange field and the blocking temperature obtained from magnetotransport measurements significantly exceed those obtained from the hysteresis loop shift.
