  A single layer ferromagnetic film magnetized in the plane of an ac current
flow, exhibits a characteristic Hall voltage with harmonic and second harmonic
components, which is attributed to the presence of spin currents with
polarization non-collinear with the magnetization. A set of 30 nm thick
permalloy (Py) films used in this study are deposited at an oblique angle with
respect to the substrate plane which induces an in-plane easy axis in the
magnetization of the initial nucleating layers of the films which is distinct
from the overall bulk magnetic properties of the film. This unusual magnetic
texture provides a platform for the direct detection of inverse spin Hall
effect in Hall bar shaped macroscopic devices at room temperatures which we
denote as Anomalous Inverse Spin Hall Effect (AISHE). Control samples
fabricated by normal deposition of permalloy with slow rotation of substrate
shows significant reduction of the harmonic Hall signal that further
substantiates the model. The analysis of the second harmonic Hall signal
corroborates the presence of spin-orbit torque arising from the unconventional
spin-currents in the single-layer ferromagnets.
