Embodiments are directed to a method of forming a magnetic stack arrangement of a laminated magnetic inductor having a high frequency peak quality factor (Q). A first magnetic stack is formed having one or more magnetic layers alternating with one or more insulating layers in a first inner region of a laminated magnetic inductor. A second magnetic stack is formed opposite a surface of the first magnetic stack in an outer region of the laminated magnetic inductor. A third magnetic stack is formed opposite a surface of the second magnetic stack in a second inner region of the laminated magnetic inductor. The insulating layers are formed such that a thickness of an insulating layer in the second magnetic stack is greater than a thickness of an insulating layer in the first magnetic stack.
