Spin-wave-mediated quantum corrections to the conductivity of thin ferromagnetic films of gadolinium

We present a study of quantum corrections to the conductivity of thin ferromagnetic gadolinium films. In situ magnetotransport measurements were performed on a series of thin films with thickness $dl150\text{ }\text{\AA{}}$. For sheet resistances ${R}_{0}\ensuremath{\le}2840\text{ }\ensuremath{\Omega}$ and temperatures $T\ensuremath{\le}30\text{ }\text{K}$, we observe a localizing, linear in temperature contribution to the conductivity in addition to the logarithmic temperature dependence expected from well-known quantum corrections in two dimensions. We show that such a linear $T$ dependence can arise from a spin-wave-mediated Altshuler-Aronov-type correction.
