Holes in nanowires have drawn significant attention in recent years becauseof the strong spin-orbit interaction, which plays an important role inconstructing Majorana zero modes and manipulating spin-orbit qubits. Here, fromthe strongly anisotropic leakage current in the spin blockade regime for adouble dot, we extract the full g-tensor and find that the spin-orbit field isin plane with an azimuthal angle of 59{\deg} to the axis of the nanowire. Thedirection of the spin-orbit field indicates a strong spin-orbit interactionalong the nanowire, which may have originated from the interface inversionasymmetry in Ge hut wires. We also demonstrate two different spin relaxationmechanisms for the holes in the Ge hut wire double dot: spin-flip cotunnelingto the leads, and spin-orbit interaction within the double dot. These resultshelp establish feasibility of a Ge-based quantum processor.
