 f spin angular momentum – is a fascinating manifestation of spin physics
  in the solid state. In ferromagnet/normal metal thin film heterostructure
 s\, pure spin currents can be generated\, e.g.\, by means of spin pumping 
 [1\,2]\, or via the application of thermal gradients in the so-called spin
  Seebeck effect [3]. An elegant scheme for detecting spin currents relies 
 on the inverse spin Hall effect: because of spin-orbit coupling\, a spin c
 urrent also induces a charge current\, which then can be detected using co
 nventional electronics [1\,2\,3]. Furthermore\, the interplay between char
 ge and spin currents gives rise to an interesting magnetoresistance effect
  in magnetic insulator/normal metal heterostructures\, the so-called spin 
 Hall magnetoresistance (SMR) effect [4]. In the talk\, I will start with a
 n introduction to pure spin current transport as well as spin Hall physics
 . I will then address the spin Hall magnetoresistance effect from an exper
 imentalist’s perspective\, and discuss which spin transport parameters c
 an be derived from SMR data. Last but not least\, I will introduce a novel
 \, non-local magnetoresistance effect mediated by magnon transport in magn
 etic insulator/normal metal nanostructures [5\,6]. This magnon-mediated ma
 gnetoresistance (MMR) can be naively understood as a non-local analogue of
  the SMR. However\, MMR and SMR exhibit qualitatively different temperatur
 e dependencies owing to the different microscopic mechanisms at work. The 
 MMR furthermore opens intriguing perspectives for spin transport on the na
 noscale.
