We address the analyticity and large time decay rates for strong solutions ofthe Hall-MHD equations. By Gevrey estimates, we show that the strong solutionwith small initial date in $H^r(\mathbb{R}^3)$ with $r>\f 52$ becomes analyticimmediately after $t>0$, and the radius of analyticity will grow like$\sqrt{t}$ in time. Upper and lower bounds on the decay of higher orderderivatives are also obtained, which extends the previous work by Chae andSchonbek (J. Differential Equations 255 (2013), 3971--3982).
