摘要：

Metastable magnetic phases in alpha-Dy2S3 induced by rotation of the single crystal in a magnetic field have been investigated. The compound alpha-Dy2S3 possesses an orthorhombic crystal structure having two crystallographically inequivalent Dy sites and shows successive antiferromagnetic transitions at T-N1 = 11.4 K and T-N2 = 6.4 K associated with various steep responses in physical properties. Anomalous enhancement of the alpha-axis magnetization from 5.4 to 8.4 mu(B)/Dy-atom has been found after a certain process of rotating the single crystal at 6 K around the b-axis in the magnetic field of 7 T perpendicular to the b-axis. This magnetic phase induced by rotating the single crystal has been considered as the same phase induced by cooling in the strong magnetic field of 18 T, which had been found in our previous work. Moreover, a certain process that combines rotating with cooling of the single crystal in the magnetic field gives rise to exchange of the features of the magnetization curves for the a-and c-direction. Consequently, the easy magnetization axis in the ac-plane switches to the c-axis from the a-axis. (C) 2017 Elsevier B.V. All rights reserved.
