Spontaneous spin polarization in quantum point contacts

We investigate ballistic transport in quantum point contacts fabricated from high mobility two-dimensional hole gas. At low temperatures conductance quantization in units of 2e2/h is observed. Incorporation of point contacts into a magnetic focusing device allows us to measure relative population of...
