Abstract

Some organic dyes of a double diazo structure, pressurized into thin films, show trapping of magnetic flux at room temperature, suggestive of the behavior of type 2 superconductors. Some also show switching from low to high electrical conductivity at a voltage threshold, like amorphous inorganic semiconductors. An applied magnetic field facilitates switching, as well as current flow after switching, in a dye that traps magnetic flux but not in a dye of almost similar structure that does not trap magnetic flux. For best results, the magnetic field should be applied before switching and in a direction perpendicular to current flow. The magnetic field effects observed in the dye films at room temperature may be analogous to "anomolous" magnetic phenomena observed in metallic superconductors and/or in superconducting Josephson junctions at low temperatures. The implied possibility of superconductive mechanisms of biomagnetic effects, and apparent relation to the electrical switching seen in wet melanin, give the findings biological relevance.

在可能成为室温超导体的电开关染料薄膜中,磁场促进导电的初步研究。
一些双重氮结构的有机染料,加压成薄膜后,在室温下表现出磁通的捕获,暗示了2型超导体的行为。有些还表现出在电压阈值下从低电导率到高电导率的转换,如无定形无机半导体。在一种能捕获磁通量的染料中,外加磁场能促进开关,以及开关后的电流流动,而在一种几乎类似结构的染料中则不能。为获得最佳效果,应在开关前施加磁场,且磁场方向应与电流垂直。在室温下在染料薄膜中观察到的磁场效应可能类似于在金属超导体和/或低温超导约瑟夫森结中观察到的“异常”磁现象。生物磁效应的超导机制的可能性,以及与湿黑色素中所见的电开关的明显关系,使研究结果具有生物学相关性。
