    • The difference between TB and TN is significant provided the thermometry used in the SQUID and neutron experiment performed similarly (both used calibrated Cernox sensors). A better approach would be to measure the temperature dependencies of the exchange bias with polarized neutron reflectometry and TN with neutron diffraction using the same thermometer-measurements planned for the future with Asterix.

    • We note that in Refs., it was concluded the size of the domain of uncompensated magnetization in the AF affected the sign and magnitude of exchange bias. This dimension is not the AF domain size we discuss in the present paper. The AF domain size refers to the size of the domain over which long range order of the AF spin lattice exists.
