Abstract We report the successful growth and characterization of Li$_9$Cr$_3$(P$_2$O$_7$)$_3$(PO$_4$)$_2$ single crystal, and investigate its magnetic properties under external magnetic fields via magnetization and heat capacity measurements. Our study reveals that Li$_9$Cr$_3$(P$_2$O$_7$)$_3$(PO$_4$)$_2$ is an easy-plane kagome ferromagnet with $S=3/2$, as evidenced by the Curie-Weiss temperature of 6 K which implies a ferromagnetic exchange coupling in the material. Under zero magnetic field, Li$_9$Cr$_3$(P$_2$O$_7$)$_3$(PO$_4$)$_2$ undergoes a magnetic transition at $T_{\rm C} = 2.7$ K from a paramagnetic state to a ferromagnetically ordered state with the magnetic moment lying in the kagome plane. By applying a $c$-axis directional magnetic field to rotate the spin alignment from the kagome plane to the $c$-axis, we observe a reduction in the magnetic transition temperature as the field is increased. We construct a magnetic phase diagram as a function of temperature and magnetic field applied parallel to the $c$-axis of Li$_9$Cr$_3$(P$_2$O$_7$)$_3$(PO$_4$)$_2$ and find that the phase boundary is linear over a certain temperature range. Regarding that theoretically, the field-induced phase transition of the spin reorientation in the easy-plane ferromagnet can be viewed as the ferromagnetic magnon Bose-Einstein condensation (BEC), the phase boundary scaling of field-induced ($B \parallel c$) magnetic transition in Li$_9$Cr$_3$(P$_2$O$_7$)$_3$(PO$_4$)$_2$ can be described as the quasi-2D magnon BEC, which has been observed in other ferromagnetic materials such as K$_2$CuF$_4$.

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.
