** Title:** On stochastic optimal control in ferromagentism

** Abstract: ** In this presentation, we study an optimal control problem for the stochastic Landau-
dLifshitz-Gilbert equation on a bounded domain in R^d (d = 1, 2, 3). We first establish existence of
a relaxed optimal control for relaxed version of the problem. As the control acts in the equation
linearly, we then establish existence of an optimal control for the underlying problem. Furthermore,
convergence of a structure presrving finite element approximation for d = 1 and physically relevant
computational studies will be discussed.
