High field transport and elastic properties of HOPG at T = 4.2 K. a c-axis magnetoresistance (R zz) as a function of magnetic field, B, oriented parallel to the c-axis in HOPG graphite. b elastic properties of HOPG for B || c at 4.2 K: the sound velocity (\(\frac{{\Delta v}}{{{v_0}}}\) in orange left y-axis) and attenuation (Δα(ω) in blue right y-axis) change for the longitudinal acoustic mode c 33 propagating along the c-axis, at a frequency f = 255 MHz. The dashed lines indicate the transition field for the different transitions labeled α, β, γ, and δ
