Anomalous magnetoresistance in detwinned EuFe2As2 |
EuFe2As2 crystal and magnetic structure (Eu atoms (yellow) and spins (blue), Fe atoms (green) and spins (red), and As atoms (celadon)), and the spin configuration of Eu2+ dependent on an external magnetic field along a (a), b (b), and c direction (c), respectively. The black arrows are the applying external magnetic field and the length of the black arrows means the magnitude of the magnetic field. The gray arrows are the original spins of Eu2+. |
