In a rare deal between two teams that competed against each other in the Stanley Cup finals last year, New Jersey shipped a fifth-round selection in the 2013 draft for Loktionov, who will be assigned to the team's American Hockey League affiliate in Albany, N.Y.
Loktionov, 22, is in his fourth professional season. He has seven goals and 14 points in 59 NHL games.
The Devils, a No. 6 seed, lost in six games to the Kings, a No. 8 seed, last June, as Los Angeles won its first Stanley Cup.
