Coplanar antiferromagnetic order in non-symmorphic crystals can induce odd-parity spin splitting, nematic order, or scalar odd-parity order, with microscopic models and 67 material candidates identified.
For the first two AFM states, Eαβγ is independent of α, implying doubly degenerate bands

Odd-parity Magnetism Driven by Antiferromagnetic Exchange
Coplanar antiferromagnetic order in non-symmorphic crystals can induce odd-parity spin splitting, nematic order, or scalar odd-parity order, with microscopic models and 67 material candidates identified.
