“…The hysteresis effect is considered to arise from the existence of some pinning potentials for a collective mode known as ''CDW condensates'' in the crystal, or some magnetic-fieldinduced ''CDW-to-normal phase transition'' of the carrier system. Similar magnetic-field-induced phase transitions have been observed in other low-dimensional materials, such as graphite 10 and ͑TMTSF͒ 2 PF 6 . 11 The detailed mechanism has, however, not yet been made clear in these materials.…”

“…The ac measurements were done over the frequency range of 50-500 kHz using a phase-sensitive detection technique. 10 High-frequency background noises and inductive signals induced by the pulsed magnetic field were eliminated using a numerical smoothing procedure on a computer. To eliminate spurious backgrounds, both the applied magnetic field and sample current ͑for dc measurements͒ were reversed and the data signals were averaged.…”

Transverse magnetoresistance and Hall effect of the charge-density-wave ͑CDW͒ material -Mo 4 O 11 have been measured at 4.2 K ͑second CDW state͒ by dc and ac methods over the frequency range 50-500 kHz in pulsed magnetic fields up to 40 T. These quantities are both reversible and frequency independent for a low-field sweep up to near 10 T ͑ϭH c ͒, beyond which an appreciable frequency-dependent hysteresis effect appears. The Cole-Cole plots of the real versus imaginary parts of the magnetoresistance at high magnetic fields show a monodispersion. The magnetic-field dependence of the real part of the ac Hall resistivity shows interesting behaviors, peaking near H c , followed by a decrease with H and a leveling off at high fields, while the imaginary components are very small and less frequency dependent. Using a multicarrier model consisting of the remaining and nested electron and hole bands, we have performed computer simulations for these dc and ac magnetotransport quantities, in satisfactory agreement with the observations. We have taken into account ͑1͒ the Zeeman effect for two types of the remaining hole and electron bands, ͑2͒ the CDW-gap narrowing of the nested electron and hole bands, ͑3͒ magnetic-field-induced CDW-to-normal phase transition in part of these nested bands, and ͑4͒ the magnetic-field-induced ''CDW oscillation'' around some mean position of the CDW condensates ͑or thermal excitation of the CDW phasons over a pinning potential͒, according to the existing CDW model.

“…However, the onset magnetic field of the density-wave state hardly depends on measurement frequency. Subsequently, Takamasu and coworkers made a more systematic study at frequencies of up to 10 MHz, and found that the frequency dependence of the real and imaginary parts of the conductivity are explained in terms of a phenomenological model for a conventional onedimensional conductor [26].…”

Whilst the realization of graphene, probably one of the best two-dimensional carrier systems to study, has attracted much research interest recently, graphite, which may be regarded as multi-layered graphene, has also been known to exhibit very interesting phenomena at high magnetic fields and low temperatures. The electron-hole system in the compensated semimetal graphite undergoes a magnetic-field-induced electronic phase transition and successive transitions, including a reentrant transition back to the normal phase, at higher magnetic fields. In this article, we review the physics of the high-magnetic-field phase of graphite and elaborate on our studies on this subject using pulsed high magnetic fields.
