a Temperature dependence of the specific heat measured by the thermal relaxation method for ErCo2 (black), ErCo1.96Fe0.04 (blue) and ErCo1.95Fe0.05 (red) alloys. b Time evolution of the sample temperature obtained using the relaxation method at the temperature where each sample shows a peak anomaly indicated by arrows (I), (II), and (III) in a. The dashed lines denote heat power for each measurement (1st (black), 2nd (blue) and 3rd (red) measurements) in b.
