mpounds, the copper ions are in the state Cu. and have one hole with spin . = 1/2 in the 3. shell. A strong superexchange interaction (via oxygen ions) between hole spins at copper sites gives rise to a three-dimensional long-range antiferromagnetic order with relatively high Neel temperatures .. =Expertise 发表于 2025-3-27 14:15:49
