Half-metallic Heusler alloys are attracting considerable attention because oftheir unique half-metallic band structures which exhibit high spin polarizationand yield huge magnetoresistance ratios. Besides serving as ferromagneticelectrodes, Heusler alloys also have the potential to host spin-chargeconversion which has been recently demonstrated in other ferromagnetic metals.Here, we report on the spin-charge conversion effect in the prototypicalHeusler alloy NiMnSb. Spin currents were injected from Y3Fe5O12 into NiMnSbfilms by spin pumping, and then the spin currents were converted to chargecurrents via spin-orbit interactions. Interestingly, an unusual charge signalwas observed with a sign change at low temperature, which can be manipulated byfilm thickness and ordering structure. It is found that the spin-chargeconversion has two contributions. First, the interfacial contribution causes anegative voltage signal, which is almost constant versus temperature. Thesecond contribution is temperature dependent because it is dominated byminority states due to thermally excited magnons in the bulk part of the film.This work provides a pathway for the manipulation of spin-charge conversion inferromagnetic metals by interface-bulk engineering for spintronic devices.
