Traditionally, the material has been regarded as a classic antiferromagnet because the magnetic moments on neighbouring manganese atoms point in opposite directions, generating a vanishing net magnetisation.

From

"Thanks to the high precision and sensitivity of our measurements, we could detect the characteristic alternating splitting of the energy levels corresponding to opposite spin states and thus demonstrate that manganese telluride is neither a conventional antiferromagnet nor a conventional ferromagnet but belongs to the new altermagnetic branch of magnetic materials," says Juraj Krempasky, beamline scientist in the Beamline Optics Group at PSI and first author of the study.

From

The topological insulator is a ferromagnet -- a type of magnet whose electrons spin the same way -- while FeTe is an antiferromagnet, whose electrons spin in alternating directions.

From

The researchers experimented with an antiferromagnet known as an orthoferrite.

From

A team of researchers led by Associate Professor Kenta Kimura of the Graduate School of Engineering at Osaka Metropolitan University investigated the phenomenon of nonreciprocal optical absorption in the magnetoelectric antiferromagnet LiNiPO4 at shortwave infrared wavelengths.
