Spin-Seebeck like signal in ferromagnetic bulk metallic glass without platinum contacts

• Thermomagnetic properties ferromagnetic bulk amorphous metal, Co85Si5Fe3B3Mo2Ni2.
• Thermopower, magnetothermopower, planar, ordinary and anomalous Nernst effect.
• Planar Nernst effect data also contain a signal similar to the spin-Seebeck signal.
• We suggest that Co85Si5Fe3B3Mo2Ni2 might have an inverse spin Hall effect.

The anomalous, ordinary, and planar Nernst effects of the ferromagnetic bulk metallic glass Co85Si5Fe3B3Mo2Ni2 are reported. The contribution of the anomalous Nernst signal when the magnetic field is oriented in the plane of the specimen is shown to be zero; yet there is an odd component to the measured signal that varies along the sample length. Even though all measurements here are made using point contacts, and no spin-sensitive Pt strips are present, the signal has similarities to the spin-Seebeck signal.
