Critical temperature T AN of the anisotropic A-type magnetic structure for EuZrO3 determined by Eq. ( 20 ). Various values of J 2 and D are tested. Empty circles: J 2 varies linearly with D . Empty squares: D = 0. In these two cases, 0 < J 2 < 0.0192 K. In Eq. ( 23 ), 4 J 2 − J 1 > 0 should be held, since χ A( T AN) > 0. When J 1 = 0, it is reckoned that J 2 = 0.0192 K. We have fixed J 2 > 0. Hence, the J 2 value is confined in the range 0 < J 2 < 0.0192 K. Empty triangles: J 2 = 0. In all the cases, the maximum T AN is 3.13 K, which is less than the experimental value 4.1 K.[ 6 ]
