Let 0<α≤2$0<\alpha \le 2$. Let 58fc5e9a3e25627eb6032" title="Click to view the MathML source">N^d${\mathbb{N}}^d$ be the d$d$-dimensional lattice equipped with the coordinate-wise partial order 584dd0" title="Click to view the MathML source">≤$\le$, where d≥1$d\ge 1$ is a fixed integer. For $n=(n_1,\dots ,n_d)\in {\mathbb{N}}^d$, define 8e42">$\left|n\right|={\prod }_{i=1}^d{n}_i$. Let e15cbef84622bfde111c8538baa9">$\{X,X_n;n\in {\mathbb{N}}^d\}$ be a field of independent and identically distributed real-valued random variables. Set $S_n={\sum }_{k\le n}{X}_k$, 8e708c87584f09a317df94154e80658">$n\in {\mathbb{N}}^d$ and write $logx={log}_e(e\vee x),x\ge 0$. This note is devoted to an extension of a strong limit theorem of Mikosch (1984). By applying an idea of Li and Chen (2014) and the classical Marcinkiewicz–Zygmund strong law of large numbers for random fields, we obtain necessary and sufficient conditions for
