Abstract ErGa3-xMnx disordered alloy is successfully prepared by the vacuum arc melting technology, and the crystal structure and magnetic properties are investigated by using the x-ray diffraction and magnetic measurements. The Rietveld structural analysis indicates that the ErGa3-xMnx crystallizes into a cubic structure with space group of Pm3m in Mn doping range of x=0-0.1. However, the disordered alloy with structural formula of Er0.8Ga2I(GaⅡ, Mn)0.4 as the second phase is separated from cubic phase for the samples with x=0.2 and 0.3, which is induced by substituting the (GaⅡ, Mn)-(GaⅡ, Mn) pair at 2e crystal position for the rare earth Er at 1a site. The lattice parameters tend to increase with Mn content increasing due to the size effect at Ga (1.30 Å) site by substituting Mn (1.40 Å) for Ga. The paramagnetic characteristic is observed by doping Mn into ErGa3 at room temperature. With Mn content increasing from x=0 to 0.1, the magnetic susceptibility χ tends to increase. This phenomenon can be due to the increase of effective potential induced by doping Mn into ErGa3. However, the magnetic susceptibility χ continues to decrease with the increase of Mn content in a range of x>0.2, which is due to the phase separation from the cubic Er(Ga, Mn)3 to the hexagonal Er0.8Ga2(Ga, Mn)0.4.

Online attention
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.
