Abstract The single crystals of NdPrFeO were successfully grown by optical floating zone method. Room temperature x-ray diffraction and Laue photograph declared the homogeneity and high quality of the crystal. The significant magnetic anisotropy and multiple magnetic transitions illustrate the complex magnetic structure. At high temperatures ( K), it shows the typical characteristics of (G, A, F) state. With the decrease of the temperature, it undergoes a first-order spin reorientation transition from (G, A, F) to (F, C, G) state in the temperature window of 45-66 K under an applied magnetic field of 0.01 T. As the temperature drops to K, a new magnetic interaction mechanism works, which results in a further enhancement of magnetization. The - phase diagram of NdPrFeO single crystal was finally constructed.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
