Distinguishing antiferromagnetic spin sublattices via the spin Seebeck effect

We measured spin Seebeck signals at the top and bottom surfaces of an antiferromagnetic Cr2 O3 film, using a Pt/Cr2 O3/Pt trilayer. Our experimental data, combined with micromagnetic simulations, clearly demonstrate that the uncompensated sublattice at the top and bottom surfaces plays a decisive ro...
