Abstract: We present the experimental study of spin rectification in parallel and series networks of ferromagnetic conductors. The networks were composed of Ni36Fe64 elements (wires) which, when subject to ferromagnetic resonance (FMR), develop a small spin-rectification photovoltage. We found that the effect of spin rectification can be modeled as an increase in resistance of the ferromagnetic elements and closely follows the usual dependence of total network resistance in series and parallel electric circuits: the total spin-rectification photovoltage in ferromagnetic wires connected in series is equal to the algebraic sum of contributions from individual wires, while in the parallel connection one needs to add the reciprocals of the individual contributions. Our results support a simple way to control and manipulate the magnitude of spin-rectification photovoltage in multi-element spintronic devices.
