TL;DR: Low-temperature magnetic properties of the p-nitrophenyl nitronyl nitroxide phases of p-NPNN were determined by measuring the specific heat, the magnetic susceptibility, and the hysteresis curve of magnetization above $^{3}\mathrm{He}$ temperature in external magnetic fields.

TL;DR: The development of an elaborate growth technique of high-crystallinity and high-mobility Cd3As2 thin films with controlled thicknesses and the observation of quantum Hall effect dependent on the film thickness is reported.

TL;DR: In this article, the carrier density control of quantum Hall states realized in thin films of DSM Cd3As2 has been investigated, where chemical doping of Zn combined with electrostatic gating has enabled to tune carrier density both over a wide range and continuously, even across the charge neutrality point.

TL;DR: This work reports surface quantum oscillation and its evolution into quantum Hall states in Cd3As2 thin films, where unconventional bulk states involve in quantized surface transport, and demonstrates surface transport controlled in film samples.

TL;DR: In this paper, the carrier-density control of quantum Hall states realized in thin films of DSM Cd3As2 has been investigated, where chemical doping of Zn combined with electrostatic gating has enabled to tune the carrier density over a wide range and continuously even across the charge neutrality point.
