41. The Hall effect is seen when a conductor is passed through a uniform magnetic field. 42. Particularly intriguing is a phenomenon, occurring at extremely low temperatures, called the fractional quantum Hall effect . 43. Both also have a quantum spin Hall effect . 44. Unlike the quantum hall effect , here no magnetic field is required to create this unique behavior. 45. Any electric current will be associated with Laughlin quasiparticles, implicated in the fractional quantum Hall effect . 46. On these scales the Hall effect becomes important. 47. Laughlin and Stoermer agreed that the fractional quantum Hall effect was unlikely to have immediate applications. 48. An altogether different source uses the fractional quantum Hall effect as a substitute for the superconductor. 49. See also the Quantum Hall effect ). 50. An alternative to Hall effect sensors with gears are sensors or encoders which use [ magnetoresistance ].
