For bipartite graphs  G1,G2, the bipartite Ramsey number br(G1,G2) is the smallest integer b such that any subgraph G of the complete bipartite graph Kb,b,either  G contains
a copy of G1 or its complement relative to Kb.b contains a copy of G2 . We obtained lower bounds of br(K2,2;Kn,n) for . for 6< n < 10

Keywords: Bipartite Ramsey numbers, lower bounds, graphs.
